Classroom 2.0

With only one slide and 156 comments this voicethread illustrates the wisdom of crowds effect of Web 2.0. I suppose we need to ask about the benefits here, and whether or not this fulfills a useful purpose. It's great to have all those voices, but frankly I got bored. Maybe it would be different if I'd initiated it, because there's something much more attractive about the comments I get as opposed to the comments others get! When I'm reading blogs, I usually tend to skip the comments unless, of course, I've left a comment and go to check to see if there's a reply. There's a sort of self-presentation thing going on here. I wonder if that's why learning blogs tend to work better than bulletin boards, the sense of ownership, of it being my space in which I perform my identity, and then later, check to see how it went down?
