I've been meaning to upgrade the Akismet module on this site for a while now. Of course, I waited so long that another option just appeared, one I've been waiting to see for a while: Mollom.
The other other project from apparent insomniac Dries Buytaert, Mollom is a content filtering service similar to Akismet. I've actually been familiar with it for a long time, as the GoPHP5 project has been running a Mollom private beta since last June. In fact, when Acquia was announced my first thought was "wait, what happened to Mollom?"
Setting up Mollom was of course simple. (There's be a problem if it wasn't.) As a service, you sign up on the Mollom web site, install the Drupal module, enter your account key, and you're done. It even provides an integrated flash-based graph of activity. Nifty.
Given how successful Mollom was on GoPHP5 (node creation forms were open to the public on a high-profile site, and I don't think I saw more than one false negative, if that, during the entire project), I have high hopes that Dries latest endeavor will be a success. It's not quite perfect, though, so here's a little feedback, in no particular order:
Dries, do you ever sleep? Or eat? Or... anything? Sheesh!
