By far! My best websites have been developed on top of the Drupal framework.

Lately, my conundrum is very specifically this:

I have re-written and am in the process of re-factoring a WPMU framework. I inherited legacy code and have been working with it for about 68 weeks for five or six hundred websites. The database does not scale and all day long, I want to bang my head against the wall! ... "if you we were using Drupal, this would be a non-issue".

Meh!

Please post links to Drupal multi-site install?
