Humorously enough, a friend and I stated rolling our own minimal blog software after realizing that a base install of Wordpress is over 6 MB.
It supports comments, multiple posting users, categories, has RSS, will let you theme it (although there is still a bunch of hardcoded HTML generation that we're working to remove for the next major revision) and is less than 300 KB installed.
