Because of a large increase in the amount of comment spam posted on this blog -- most of it probably done by machines -- I've decided to turn on TypePad's authentication feature. I value legitimate comments, so regret to have to put you through this extra step.
Well, I just got around to testing this and, instead of having you identify a graphically displayed word, it makes you register. That's too much to ask, so I'm going back to the moderated version and just keep deleting the 10-15 spam comments per day. Arghh.
