I've decided to switch to Disqus for comments on this site. I've gotten more than a little tired of all the spammers trying to create accounts, bots with fantastic names such as drugs4less, fred945willaams45, and qoxmncberuy. I'm going to be making an effort to post more often on my side, and hopefully this will increase audience participation.
Please let me know if you have any trouble attempting to comment using Disqus. I looked into Facebook comments, which I think would reduce spam even more, but there were a lot more hoops to jump through, and unlike Disqus, there is no direct Drupal integration.
