I am receiving Tweets (that's a Twitter message) from friends as they travel the world. They are all traveling from America to other parts of the world. The map above shows the homes of Twitter users. Looks like Europe is inundated and the US isn't too far behind. I found this map in an interesting article recommended by Lois Lindell, Why We Twitter: Understanding Microblogging Usage and Communities.
It's interesting to think about how we can communicate at the touch of a button. I received a tweet from Howard Reingold asking if anyone knew of "Any ideas on using Twitter in classroom besides backchannel." He said that students could twitter insights, comments and questions during class discussions. That's an interesting idea.
What other kinds of educational applications are there? Is this just a solution looking for a problem, or is it a new utility that will allow us to do things that will expand our learning experiences?
What do you think? Does Twitter have any educational value?
