Just so you know - I found some money, and I've hired a professional to move this site out of Drupal and into Joomla.
It will may take a few weeks, but when the switch happens, most of the comments lost when this site was hacked will be returned. Also, the redesign will have the following features:
* Users will be able to create their own blogs. (A la DailyKos.)
* A forum integration into the site. (A la DemocraticUnderground.)
* Enough Spam filtering features to discourage the most die-hard Viagra marketer.
Brainshrub.com will become a community-blog. Where it goes from there will be entirely up to you.
