BLOG:CMS is the most complete, feature-packed, personal publishing system on the market, developed by Radek Hul?n. It includes state-of-the-art weblog, forum, wiki engine, news aggregator (atom / rss), and photo gallery.
BLOG:CMS is probably the only system that is not only w3c valid, but also ships with application/xhtml+xml MIME type by default, for top performance on modern browsers like Mozilla, Firefox, Safari and Opera. But BLOG:CMS will also automatically supply older standard, text/html, to browsers which cannot handle this, like obsolete Microsoft Internet Explorer.
WordPress is a state-of-the-art semantic personal publishing platform with a focus on aesthetics, web standards, and usability. What a mouthful. WordPress is both free and priceless at the same time.
