Twitter is a social networking phenomenon where people tell their friends and followers what they are doing within a limit of 140 characters.

What has been most interesting about Twitter, for me at least, is all the other applications that are being developed around it.

 For example, the ATL Insider street team found TwitterLocal.net a site where you can enter your zip code and follow Tweets from people in your local area.

 I also located Summize, a type of search engine to find conversations. Click here to see what people are saying about Atlanta right now!
