PriceLiveJournal, Blosxom, and Blogger are completely free. Blogger has an upgrade path, however: for advanced features such as RSS and Weblogs.com notification, you have to pay for Blogger Pro (now $35 per year, will be $50 per year, once all the planned features are available). LiveJournal sells a subscription ($5 for 2 months, $15 for 6 months, $25 for 12 months) that provides you with benefits such as a livejournal.com email address, text messaging, advanced customization, and faster servers.
Radio UserLand has a free 30-day trial and costs $39.95 per year. This gets you free software updates and blog hosting. You can continue to use the software after your subscription expires, but you won't receive updates and you must make separate arrangements to host your blog.Greymatter is completely free. The author accepts donations through PayPal, however. This may seem odd at first, but it enables those who can afford to pay for their software to name their own price. If you can't afford to pay, you can still use the software and not be a criminal.Movable Type is free for personal and non-profit use. Commercial users need a $150 commercial license. Personal and non-profit users can donate in a PBS-like model — $20 gets you a key to be listed on "Recently Updated Movable Type Blogs" and $45 gets you all that and support for instant messaging within certain hours.
Manila is part of the $899 commercial product called Frontier. Manila is the blog hosting and management part of the larger Frontier content-management system. You can get a free 60-day trial of Manila from http://manila.userland.com/. Slash and Zope are both open source software. You can download, install, and use them without paying. Slash is released under the GNU General Public License (GPL), while Zope is released under the Zope Public License (ZPL).
