I'm sure this has been asked, but I figured I'd start a fresh thread. How many of you teachers out there use a social netwrok for teachers. This, of course, I mean as opposed to "tresspassing" on the networks of your students - such as Facebook or MySpace.
I don't currently use one but i figure, since so many students do, it would be worth taking advantage of a network for teachers. The way I see it, it's like a free teacher website.
Any thoughts... successes... failures in this area?
