I am seriously considering deploying new weblog software. I don't have the time to maintain my half-assed stuff between my job and the taupe sekrit projecktz. I am currently looking at Drupal, Nucleus, and Grey Matter. I am not considering Movable Type because of its restrictive license. The aforementioned packages are all GPL, which is what I would prefer (although BSD, MPL, and other OSI-approved licenses would be fine too). Conveniently I need to play with some of these packages to do some research for work. No doubt there are others out there that would serve my needs, but those look to be the most fully-featured and flexible. Ideally the source would be in Perl or PHP so I can pretend that I would actually read it at some point.
