For me, it's a time issue. I don't have time to moderate blog comments on my own blog, so I disabled comments. Some people might post some really awesome comments, but a small percentage of people ruin the whole thing. So moderation is a necessity if you're going to allow comments. HN obviously allows comments, but it's because HN has dedicated moderators (thank you!). Most people are not trolls. But there are enough trolls who pee in the pool that many pools have had to be closed.
