I'll create a Diigo group to aggregate links and create ad hoc discussion groups (teacher or student initiated).

We'll also aggregate links that respect the class tagging protocol here. Everything on Diigo has RSS feeds so I can move the content around any way I like. I'll likely have feed windows to the group discussions and link archive on the class blog. In the past I've done something close to this using delicious but delicious doesn't have the group discussion feature built in.

You might also use join.me to play presentation tennis with everyone in class; live! Have everyone download the app. ;-)
