it's been just over 24 hours since I switched to Mollom for antispam on the blog. According to Mollom:
So far, Mollom has blocked or moderated 665 messages on your website of which you moderated 10.08% yourself.
That's 67 spam comments I've had to moderate in 24 hours. Not good. Hopefully it gets better as it warms up and gets tuned to the specific types of crap that gets sent my way...
