Geeklog is an open source CMS/weblog application, written in PHP and using MySQL or MS SQL as the database. The current core development group consists of five people, with a further 10-20 people contributing source code, plugins, and other add-ons on a regular basis. The community on www.geeklog.net hovers at around 150 active users, i.e. those that log into the site and participate in discussions. We also have some active international communities in Japan, Germany, Poland, and France. The Japanese community even published a book about Geeklog. While Geeklog may be one of the lesser known CMS, it does power a few high-profile sites, e.g. Groklaw. We also know that it is used quite a bit in company intranets and as a web application framework.
