 Replying to [comment:2 ryan]:
 > What's in $sql?  category!__in accepts an array of category IDs.  If you
 want to do intersections, use category!__and.

 $sql was a constantly changing text string modeled after:
 http://codex.wordpress.org/Template_Tags/query_posts#Category_Parameters

 It would appear that this documentation is misleading. I just tried using
 a normal array and it worked perfectly!
