For all of my newer readers, I also post to a group blog called Collaboratory, which was originally the brainchild of Sean (who, incidentally, is the owner of the first blog I ever saw, so in a sense he's to blame for all the mischief I do here). Anyway, Collaboratory tends to go through spikes of activity when I and my fellow members post a lot and then we slacken off, for no particular reason. The idea of the site is to both generate conversation and just put up neat stuff, either in seriousness or in fun -- kind of a smaller-scale MeFi. Go have a look, and if anyone's interested in joining, drop Sean a line. He's kind of the "Captain" of the thing.
