I find that, now that I have a blog, I feel obligated to post stuff in it periodically. The fact that I know very well that nobody but me reads it has little effect on this. This results in my putting up posts that are just lists of links, out of a lack of anything worth saying. This does have a nice side-effect, though--now I can find that cool link I saw the other day, even if I've forgotten where I found it.
