I ran across this image on Flickr. I’m posting it here on my blog for sharing and also so that I don’t lose it. I think it would be perfect for printing and posting on a classroom wall for anyone using social media in the classroom.

Kudos to the group for the content and Mitch Norris for the simple, yet effective, design.
