The no word verification thing on comments was good for about a week or two. I don't get huge amounts of spam, but enough to annoy me after two weeks. Spam is bad enough, but having it archived on a hard disk somewhere in my comments section goes against my basic don't waste principles. And I don't feel like monitoring comments or cleaning out ridiculous stuff.
