Hello, I'm a @eddieyoon, a founder of Tweetple.com. Tweetple.com is an interest-based social networking service on top of the Twitter.
As a BETA service, I've started school-based networking service firstly - http://school.tweetple.com/about/ during worldcup 2010.. Currently, I'm caching all results locally... to reduce api calls. Please review my earnest request as soon as possible.. Thanks.
