Applications for Education
I've written about using chat rooms and backchannels in the classroom quite a bit over the last couple of years. My most recent post on the topic can be found here. SimpleMeet.Me could be used as a place for students to brainstorm and share ideas about a topic. It could also be used as a simple help forum for students to ask questions of each other and of you.
