I, for one, don't read anyone's tweets. One of my personal heroes--who works in a field I know a heck of a lot more about than astronomy--is all over the Twitter thing, and I don't read his tweets, either. I find the whole idea of Twitter annoying, honestly. While I sometimes read that person's blog, because it's frequently a beautiful piece of writing, I don't always and it's the one I follow most. My participatory internet has always been largely here, ever since I first got here. Heck, I generally spend more time here than on Facebook.
