Recently, we were getting more comment spam on our experimental Drupal-site diveheads.com which Akismet failed to intercept. A good reason to try out Mollom, the new spam-fighter on the block. Mollom has been around now for a couple of months and is avalaible in three popular flavors: Drupal, Wordpress and Joomla.
We expect a lot from a SaaS (Software as a Service) founded by Dries Buytaert and we already read positive reactions on other blogs. The only thing which kept us from using it before was the dreadful CAPTCHA. But the captcha is only used when Mollom is not sure if it's SPAM or HAM (not spam), so most of the time users shouldn't be seeing the captcha.
We are testing Mollom now on diveheads.com. This site attracts loads of spambots - about a hundred spam attempts daily according to the mollom graph beneath, which is directly available from your Drupal admin interface. That's 574 attempts in one week since I started using Mollom, and until now not one spam attempt slipped through. Not bad, and certainly better than Akismet which I used earlier.

By the way: CAPTCHA stands for 'Completely Automated Public Turing test to tell Computers and Humans Apart'.
