+1 Can't agree more.  I joined the GM academy game because they have interesting conversations on topics that I'd like to read.  But I had to drop it because I'd have 10-20 notifications whenever I log in to the site (which is about once an hour, it seems...).  When I get notifications, I want it to be for things I specifically subscribed to, or things that I posted (scripts or forum requests).  Not a bunch of responses on a topic I'm not interested in.  As for campaigns, if we haven an active forum, I'd rather just go look at it before the next game and see what's new.
