Slideshare for Peer-2-Peer Commentary

Slideshare provides many powerpoints on a range of topics in a Web 2.0 environment. there are quite a few on Web 2.0 itself, building better Powerpoints, etc. Even more importantly for instruction, students can place their Powerpoints on Slideshare and receive comments on every slide. If there's a way to make a private channel, this could be quite useful. --LBB
