For those of you who don't know why e-mail is down, here is the reason: http://www.umich.edu/PowerOutage.html
As many of you obviosuly know, this is a serious problewm; personally I've had two group meetings/projects disrupted or made impossible by the incommunication. It sure would be nice if those classes had a blogosphere like this one, then we could probably communicate through there. But then I wonder, could there come a time when a class having a "blogosphere" would be a standard thing? How would it be moderated in terms of sharing information on homework, for instance? Where would the line be? There would be many issues, for sure. But right now it seems it would be really cool if all my classes had a "blogosphere."
