Movable Type
Movable Type is a blog engine with an interesting history. It is currently open source, but prior to version 4, it was proprietary software that required a license for use.
Technical Details
It is written in Perl and can use a variety of database back-ends, including MySQL.
Formatting
MovableType has a very nice WYSIWYG editor, but it also supports Markdown and Textile formatting syntaxes.
Publishing
Movable Type has four different ways to publish blog entries and website pages:
- Static
- Publish queue
- Dynamic
- Manual
- Do not publish
Plugins
MovableType supports a wide variety of plugins, though perhaps not as many as Wordpress.
