| Digg Starts Nofollow-ing Links That It Doesn't Trust | Top |
| Digg announced a seemingly small, but rather interesting change on its blog today: It has added a “rel=nofollow” tag to every link on the site that it doesn’t trust. What this means is that all the spammers who submit their stories to Digg, are now basically out of luck. Sure, all spammer who submit something to Digg hope that it hits the frontpage and brings a rush of traffic. But more important to them are the links associated with Digg. If a story is popular on Digg, it will also likely garner quite a few links back to it. But even if it doesn’t become popular, the link coming from Digg itself gives some weight to the spammy URL in a search engine crawler’s eyes. Digg using nofollow has been a subject of debate since at least 2007 , when the service was exploding with popularity. Around that time, Wikipedia decided to use nofollow for all of its outbound links. But what’s interesting here is that Digg isn’t adding nofollow to all of its links, and instead is only doing it for the untrusted ones. “ This work was done in consultation with leading experts from the SEO/SEM and link spam fields, in an effort to lookout for the interests of content providers and the Digg community ,” Digg’s John Quinn writes today. This would seem to suggest that company realizes it’s still in the interest of most content providers to get the link juice that comes from Digg. It would also seem to suggest that it doesn’t want firestorm of controversy similar to the one it created with the DiggBar . This move comes at an interesting time for Digg, as sites like Bit.ly look to be setting up to battle for who has the most interesting link data on the Internet. Twitter itself has been testing out the tracking of links from its site, though it claims to be just doing so for internal product purposes. How Digg judges which sites they trust, they don’t say. But one would have to assume that these sites are different from the ones that are straight-up blocked from the service for being spammy. Untrusted links in comments, profiles and story pages will also get the nofollow tag as well.

| NetBase Thinks You Can Get Rid Of Jews With Alcohol And Salt | Top |
| This morning I wrote about NetBase Solutions’ healthBase, a semantic search engine that aggregates medical content from millions of authoritative health sites including WebMD, Wikipedia, and PubMed. But is it a semantic engine or an anti-semitic search engine? Several of our readers tested out the site and found that healthBase’s semantic search engine has some major glitches (see the comments). One of the most unfortunate examples is when you type in a search for “AIDS,” one of the listed causes of the disease is “Jew.” Really. The ridiculousness continues. When you click on Jew, you can see proper “Treatments” for Jews, “Drugs And Medications” for Jews and “Complications” for Jews. Apparently, “alcohol” and “coarse salt” are treatments to get rid of Jews, as is Dr. Pepper! Who knew? I’ve included the screenshots of the results below if you don’t believe me. Now, I don’t think that healthBase is being intentionally anti-semitic, but for a technology which is supposed to understand the nuances of human language, this is about a big a fail as you can get. It is plainly obvious that its technology needs to be fixed before it is parsed out to other companies and media corporations. I emailed NetBase to figure out exactly how this could appear and this is the response I received: This is an unfortunate example of homonymy, i.e. words that have different meanings. The showcase was not configured to distinguish between the disease "AIDS" and the verb "aids" (as in aiding someone). If you click on the result "Jew" you see a sentence from a Wikipedia page about 7th Century history: "Hispano-Visigothic king Egica accuses the Jews of aiding the Muslims, and sentences all Jews to slavery. " Although Wikipedia contains a lot of great health information it also contains non-health related information (like this one) that is hard to filter out. Personally, I think such basic distinctions should have been ironed out before launching the site. This is just the most flagrant example of site giving non-health answers to health-related questions. If you look at the pros of AIDS (yes, it thinks here are pros to having AIDS), it comically lists the “Spanish Civil War.” One of the causes of hemorrhoids is “Bronco” (I don’t even want to know). HealthBase is touted to be a showcase for NetBase’s semantic technology, which can supposedly understand language. Clearly, it doesn’t understand language well enough. And if the technology is going to be peddled to other companies to be used to power additional search engines, it needs to be improved immediately.

| Google Voice Alternative Line2 Is Now Live On The App Store | Top |
| The Apple/Google Voice fiasco just got more interesting. Toktumi , a startup that lets small businesses build office-caliber phone systems with their mobile phones and computers, just had its application Line2 approved by Apple — nearly three months after it was originally submitted. The powerful service allows business employees to assign two phone numbers to their iPhone: one that they can give to family and friends, and another that can be given to business contacts, with features that allow for call filtering and a professional-grade voicemail system. But it’s also notable for its many similarities to Google Voice, an application that Apple has kept out of the App Store for months now. The story so far: late last July, Apple abruptly pulled all third party Google Voice applications from the App Store, explaining that they somehow were duplicating the iPhone’s native functionality. Later that day, we broke the news that Google’s official Google Voice client had been barred from the App Store, sparking a media storm and a FCC inquiry into Apple’s rationale for the ban. Line2, an iPhone client that lets you easily tap into the Toktumi service, got caught in the crossfire . From a technical standpoint the application is quite similar to Google Voice: both services allow you to hand out a ‘virtual number’ to contacts. When they call, the service can either relay the call to your ‘real’ number (the AT&T number assigned to your iPhone), or it can send it to voicemail, depending on the way you’ve set up your call filters. You can also use both services to make cheap long distance calls. In fact, the Line2 app was built by developer Sean Kovacs — the same developer who built GV Mobile, one of the handful of third party Google Voice apps that Apple pulled. But there are some key differences. For one, Toktumi doesn’t include support for SMS at all; Google Voice does. And Toktumi costs $14.95 a month, while Google Voice is free. Toktumi is also marketing its service to a very different audience: while Google Voice is trying to let you use a single phone number for everything, Toktumi wants to give small business employees who lack a dedicated work line the flexibility to use two phone numbers from the same mobile phone, and includes some features that Google Voice doesn’t. Here’s how we previously described it: Line2 would allow users to use two different numbers with their iPhones — one which they could hand out for business calls, and the other for personal. This setup would allow employees to keep their personal numbers private, and also allows businesses to set up professional features on the business line, with features like an phone directory ("Press 1 for sales…") and a single support number that calls the mobile phones of multiple employees. Even with those differences, Toktumi CEO Peter Sisson says that many consumers do actually use the service as an alternative to Google Voice — if you just hand out your Toktumi number to everyone, you can use the service’s filtering options to manage your calls much as you would with Google’s service (he does note that Toktumi’s filtering is less flexible than Google’s, but it should be sufficient for most people). Soon after the Google Voice story broke, Sisson grew concerned that his application’s similarities might keep it from being accepted to the App Store, so he attempted to reach out to Apple executive Phil Schiller. Schiller got back to him, saying that he would have an answer soon. Then the FCC launched its inquiry, and Apple went silent. Sisson says he’s been pestering Apple over the last month, and it looks like his persistence worked. It’s great news to hear that Line2 has been accepted, and it may indicate that Apple is coming closer to accepting Google Voice — given Apple’s approval of Vonage this morning, it the App Store may even have some new policies in place regarding this kind of app (though details on the Vonage app are still sparse). Also worth noting: Line2 clearly “replaces” the phone’s Voicemail and keyboard in the same way Apple complained about in its FCC response about Google Voice (this claim has always been laughable). If Apple still won’t approve Google Voice after this, it will be clear, as if it wasn’t already, that it’s not worried about the user experience — it’s worried about Google. If you’d like to try Toktumi out for yourself, visit Line2.com , and the first 200 US-based users to sign up using the promo code 743623718 will be able to access 3 months of unlimited US/Canada calling and cheap international calls, as well as Toktumi’s other features like a professional-grade voicemail system.

| Yelp Is Growing 80 Percent A Year, While Citysearch Remains Flat | Top |
| Say what you will about the quality of the reviews on Yelp or the lengths it will go to get verboten features into its iPhone app, it has made the jump from Web 2.0 darling to a mainstream service. Over the past year, Yelp has nearly doubled its U.S. audience, while incumbent CitySearch has remained flat. In July, Yelp had 8.6 million unique U.S. visitors, up 80 percent from a year ago. Citysearch, on the other hand, literally had zero growth, staying at 15.4 million uniques, although it bottomed at 13 million in April and has come back up since then (comScore). Yelp also has the No. 1 travel app on the iPhone (it is No. 26 overall). Whereas Citysearch’s similar iPhone app is not even in the top 20 travel apps. Yelp’s pageviews and average time spent per user on the site are also up 150 percent and 22 percent, respectively. In fact, the 3.3 average minutes per visitor on Yelp is above Citysearch’s 2.3 minute average. But comScore shows a steep drop in both pageviews and average time spent starting in May, with a leveling off in July. Citysearch experienced similar drops. (See charts below). It’s hard to say what is causing these drops. It could be that people are not finding what they are looking for, or the opposite, that they are finding what they need faster due to better site design. I suspect it has something to do with the latter. For instance, a much-improved Citysearch redesign went site-wide in March and Yelp is constantly tweaking its site. Update : Kara Nortman, the executive who runs Citysearch, says that the pageview numbers are down slightly, but not as much as comScore suggests. Part of this has to do with Citysearch actually going through the site and “pulling out pages that are not great consumer experiences,” which hurts SEO, but improves the site overall. Citysearch is also trying to reduce the number of searches it takes ti get to what you want, which also causes pageviews to drop. I asked Yelp CEO Jeremy Stoppelman about the pageview situation, and he sent me an internal Google Analytics chart pasted at bottom of this post). “As you can see we’ve continued to grow pageviews smoothly throughout the summer,” he says, “so it looks like the effect Comscore is reporting is spurious.” There is definitely a discrepancy there. Stoppleman also says that worldwide Yelp did 157 million pageviews in August (although he thinks that is becoming a less a meaningful metric as Ajax redesigns reduce the need for page refreshes) and more than 25 million unique visitors. (The comScore numbers cited above are only for the U.S.) Yelp came out with a major update for its iPhone app in April, right about the time the pageviews started to allegedly decline. But Stoppelman doesn’t think that is it either. There might be some shift over to mobile, but he’s seeing the following trends: Mobile usage for us is lowest early in the week and climbs throughout, peaking on Saturday. Desktop web usage (especially contributions) tends to be highest on Monday or Tuesday (though Yelp.com reader traffic sometimes peaks on Fridays as people plan their weekend in the office ;). No matter which way you cut the numbers, though, Yelp is gaining fast on Citysearch. Update “I worry about everyone,” says Citysearch’s Nortman. “I think you'll start to see some pretty strategic initiatives roll out across the web and mobile. We have this new neighborhood platform in place. We have to fill it up with trusted content.” That is how Citysearch will try to stand apart, by having reviews and other content that is more trustworthy than Yelp’s. Which site do you trust more?

| Android Now Plays Foursquare Too | Top |
| Foursquare has been all the rage in the early adopter mobile space the past several months . And it has been peeking outside of the early adopter crowd with things such as local bars offering promotions for Foursquare usage. But it has still been held back a bit by the fact that it has only had an iPhone app and a somewhat clunky mobile web interface. And Foursquare understood that, so it called for developers to help build its app for the other mobile platforms. Today, the first of those is ready to go: Foursquare for Android . Work on the project started back in April and was mainly coded by Joe LaPenna and Chris Brummel in their spare time. It started as a project to first reverse engineer the iPhone API, and then migrate to Android using Foursquare’s beta API, LaPenna tells us. After a few months of work, the duo and Foursquare’s Naveen Selvadurai (who has been managing it from the service’s side) feels its now feature-complete and ready for distribution. Users who have played with the iPhone version should feel at home with this app. But it has a few features that the iPhone version doesn’t, such as integrated maps and a one-click check-in process. Other areas like the friends check-in list and the page to display your badges are largely the same as the iPhone version, but the app has the distinctive Android look and feel. One advantage the Android platform has over the iPhone is that applications can run in the background. But Foursquare for Android chooses not to take advantage of that, and instead opts for speed and better battery life. “ No “location aware” always-on background services or application bloat to drain your battery over the course of the night, ” is how they phrase it. Since Foursquare is all about manually checking-in places, that makes sense. With the app now complete, the next revisions will focus on performance and UI, LaPenna says. But there are also some new features that both they and Foursquare have planned. “ We of course plan on adding features to the app but we’re not sure what order we’re going to tackle them in, ” LaPenna says. Having another mobile application for Foursquare should certainly help with its adoption. And Android is especially key since a lot of geeky early adopters have Android phones. There is also work being done on a BlackBerry app and a Windows Mobile app. The latter I’ve seen in action, as my friend Anand Iyer has been working on it. It has a few great features also not found on the iPhone app including the ability to ping you if three of your friends check-in somewhere that you are not. And placing your friends on an actual map to show where they are (think Latitude). One really nice thing about the new Android app is that it’s open-source. LaPenna and Brummel have already had plenty of others help in building it. You can find out more about it on the Google Code page for the project. They’ve also written up some documentation for first-time Foursquare Android users. The Android Foursquare app is available in the Android Market right now for free, or you can grab the app from the Google Code page and install it yourself. Update : DailyFinance published some other interesting information today in a profile of Foursquare. The most interesting part is that Foursquare is preparing to announce a round of seed funding. We’ve heard that as well from a couple sources. From what we hear, the company is actually looking for less money than some investors are offering. Look for a low seven figure seed round to be announced in the coming weeks. And one name that is continually thrown around as being involved is Union Square Ventures’ Fred Wilson . And where he is putting money, you can often find Spark Capital’s Bijan Sabet close by as well. Nothing confirmed yet, that’s just what we’re hearing.
