Lyceum is a hawt open-source, secure, scalable (up to 200,000 users!) blogsphere framework, just released by ibiblio. Basically, install your own blogger.com. It’s been in development for a while and gone through a myriad of developers, including myself, and now two of the most talented people I know — Fred Stutzman and John Joseph Bachir — have just put out a first release. So download it, get a group of friends together, install, and set up your own blogging community.
