It's seems I broke my comments! I experimented with installing Intense Debate for comments, decided I didn't like it, and then uninstalled it. Now it seems that there's no way to leave a comment on my new posts. I've been trying to figure out how to get that little "comments" link back at the bottom of the post with no luck. If anyone knows how to fix this, please email me. Thanks!
ETA: Comments are back! I guess I just can't get them for the last big post I did, which is a shame. Oh well.
