I was very skeptical about Twitter at first, but it's turned into my most important way to hear from my "personal learning network." I started by finding a colleague who I admire and trust, and I "followed" several folks he was following, and then it steamrolled from there. It doesn't take me very long to scan my "feed" every day, and I always walk away with a few great articles/ideas.
In case you didn't know, Steve maintains a twitter feed for items related to this blog at @highschoolpsych
Charlie Blair-Broeker attended this session and shared a great "data collection" he's done related to Twitter. Charlie used the search features in twitter to gather student comments about AP Psychology, and they are interesting, funny, sometimes perplexing, but always revealing. You should be able to access the links below to .ppt slides Charlie put together (thanks Charlie! Please add a comment if I forgot anything?)
