An extended post by a former product manager for Movable Type, comparing the fortunes of Six Apart and WordPress. Some interesting business insights, for example, in how WP made gains in the corporate blogging world, a realm that usually doesn't seem relevant to the livelihood of  blogging software companies. Turns out it is.

Bonus: In a footnote, there's an interesting bit of gossip about the Huffington Post and Movable Type.
