As I said elswhere, I typically get my interesting facts and articles from Twitter. My main interests are higher ed, technical ed, and teaching with games, among other things.
So, my question to you is: Whom do you follow that gives you the best bang for your buck? Who do you get the best articles from? Who passes on the best resources? Who comes up with the best insights? Say...the top three?
Here are mine: @edudemic - I consistently get awesome articles from this site! (The 7 Habits of Highly Effective Educators) @gamasutra - Awesome games-related information with a techie bent @Metaverse - Everything related to virtual worlds
