You're going to get more posts from me about Twitter. I've started a new keyword label/tag for my blog. I'll try to focus my selection on articles that address Twitter's relevance for educators and students.
Here are a couple more today:
1. My own blog post: why I'm a fan after 1 week trial of twitter.
2. Why You Should Be on Twitter: "Don't listen to the critics. Twitter is a great forum for communication and community building." It's a long-ish article but if you're an educator concerned about the use of twitter by students both inside and out of the classroom, please read the whole thing. "...rather than engaging in forms of unneeded media panic, we need more thoughtful, more flexible accounts of how media work."
