Okay, I'll buy that. Still not sure I am sold on it for personal usage, but I very much see how it would be useful in a classroom and with the blogging workshop I am to attend. Speaking of the workshop, we were all issued invitations to post as well as comment on the facilitator blog. That makes the whole thing more useful in my estimation. What good is a collaborative blog workshop when attendees can not post questions, comments, and issues we hope to raise?
