Matt Gemmell disabled comments, and is happy with the decision. I agree with his points, but would add a significant (to me) one:
Without comments and stats, my blog feels mine. I'm the only person that can post content here, and I have no idea how many people read or see what I post.
Sure, some would say it's antisocial, but I don't think so. Whatever it is, it's me, and when I post stuff here (or photos on the ephemera section), I don't pause to consider responses or interest in what I'm posting. And that's a liberating thing.
