Trending topics on Twitter are useful to catch up with the interesting happenings of the moment. We at MyBlogLog also launched Hot Topics a while back, showing a moving list of the hottest topics that people are buzzing about in the MyBlogLog universe.

One of the key problems that is prominent in these trending topics is low relevance as these systems do not consider user interests. Ramanand did a tweet yesterday, wishing for “Trending topics for people I follow” which encouraged me to do this hack:

Twitter Trends hack presents the trending topics in your friends’ stream on twitter. Wanna know why a topic is trending in your network? Just check out the recent hot tweets from your friends. It uses OAuth. No passwords required . IPL (A cricket league in India) is the buzzing topic in my friends’ stream right now. Find out what is hot for you: Try here.

It took me just a couple of hours to complete the hack, all because of simple Twitter APIs, Tweetapp framework and App Engine. OAuth integration was very easy with Tweetapp. The hack analyzes recent two hundred tweets from your friends, finds keywords out of the stream and those referenced with more frequency are trending topics for you.

This hack is just a proof of concept. It is no where close to a perfect personalized topic trends. In ideal world, I would like to build user interest profiles, consider demographics and accordingly show trends. But, it will no longer remain a hack then

Update (24th April): Twitter has re-enabled OAuth. Try out twitter trends now
.
Update (22nd April): An OAuth security issue has been discovered and several OAuth services including twitter have disabled it temporarily. You cannot try the hack right now

Twitter has become a powerful medium for viral marketing and bringing traffic to a website. My hack: retweetrank, went viral all due to twitter. Tweets by Robert Scoble, Tim O’Reilly, Guy Kawasaki and tons of others (600+) made it easy for retweetrank to cross 30,000 users within 10 days.

One of the notable thing was the spike in site traffic after Scobleizer tweeted the link. Below is the graph showing requests/sec.

Here I coin (:P) a term: “Scobleizer effect“:

“Scobleizer effect is the phenomenon of a popular twitter user tweeting a link of a smaller site, causing a sudden enormous spike in the site traffic. The link spreads rapidly with several users retweeting the same and results in more small traffic spikes.”

Thanks to appengine, I need not worry about scaling.

Obama is the most followed twitter user, but who is producing the most interesting content across the twittersphere lately?

Retweets are great indication of the originator’s topical influence and the audience’s interest. Recently, after reading a post “Are You Retweetable“, from Todd Sampson (co-founder MyBlogLog), I thought of creating a quick hack, Retweetrank, for ranking twitter users based on the number of retweets.

Retweetrank lets you find rank of any twitter user. With the rank, latest retweets of the user are shown and an RSS feed can also be grabbed for the same. Monitoring retweets can provide a better understanding of audience to the originator while others can see the most interesting tweets of a user.

The top ranked twitter users, who have been most retweeted recently, are listed in the leaderboard. They are the once producing most interesting content across the twittersphere.

Find your retweet rank now.

Retweetrank searches the public timelines of twitter users through the twitter APIs and is deployed on google appengine.

Update (Jan 11): As Ian Kennedy suggested below in the comments, here is a greasemonkey script to see recent retweets for any user in the twitter sidebar.

Webaroo has raised $10 million in a recent round of funding for its product SMSGupshup. Webaroo was founded by IIT Bombay alumnus and serial entrepreneurs Rakesh Mathur (founder of Armedia, Junglee, Stratify) and Beerud Sheth (founder of Elance) in 2004. Webaroo is one of the incubatees of SINE, IIT Bombay.

I was an intern at Webaroo, contributed to the personalization logic of its products, when they were under development.

SMS GupShup is mobile group SMS service that allows users to create mobile communities and broadcast messages to them, similar to twitter, but more like yahoo/google groups for mobile. Currently, GupShup sends SMS messages only to Indian mobile phone numbers. It is being used by over 300,000 publishers sending around 10M messages per day. SMS to mobile devices is one of the major costs for Webaroo.

Webaroo started with their product for offline browsing, which didn’t strike the market well, even after a couple of years of the launch. With Google gears competition, its life ahead, is even tougher. I think one of the reasons why webaroo couldn’t pick up is due to the focus on caching static content, while google gears, powered easy caching and sync of dynamic content. Remember The Milk and Google reader are my favorite apps which I use over google gears.

Earlier, Rakesh Mathur with other founders, sold Junglee to Amazon in 1998 for about $250 million. Junglee had Stanford professor Jeff Ullman on their board, who was also advising Google folks that time. Interestingly, after making a good money, Rakesh Mathur & team approached their friends Larry Page and Sergey Brin to acquire Google. But the deal could not happen as Sergey was looking for a ten digit price.

Today, while looking around MyBlogLog: New with me admin, I was stunned to see no updates from Twitter since last couple of hours and all twitter requests are generating 503 errors. Got relieved, when I found, nothing is wrong with our twitter crawlers rather twitter is down.

In case you haven’t noticed, twitter was down for more than a couple of hours, precisely from 22:12:15 (5 Apr) to 00:42:46 (6 Apr) PST.
