There are many educators and people in general who think Twitter is just for nonsense personal types of things. However, I must say that since 2007, it has provided me with insights, connections, resources that go much beyond "in the bathroom", "at the airport", "at home" types of prepositional tweets.
If you start following the right tribe of your interest, magic is likely to occur. I'd say, professional magic. If you don't know where to start, a while ago, I invested some time to create a page with the basics of Twitter for educators that might give you a boost in this microcosmus of possibilities.

Well, all that to invite you to join twitter conversations using the hashtag #edchat. Though Twitter is meant to be an asynchronous tool, there's always a nice twist people imagine, mainly educators! A group of educators decided for a specific date and time for these educational discussions in Twitter, and now it became a live feast. For all the details on what a hashtag is, how it works, and how you can participate in the Tuesdays #edchats, take a look at: http://teacherbootcamp.edublogs.org/2009/08/18/edchat-join-the-conversation/
Your tweetlife will never be the same...
