Yes, I am still here.

After about three weeks of allowing anonymous comments, I am disabling this feature again. I don't think there was a significant increase of comments, but there have been two cases of trolling and two bits of spam.

Remember: comment email addresses are scrambled. Humans can read it, spiders have a bit more trouble. And it's not that hard to fake an email address.

Update: I've deleted the two spam comments, but I've left in the anonymous all-caps abuse.
