The WordPress application for WP7 just arrived in the Marketplace. Apparently WordPress thinks WP7 is so good it deserves its own website – http://windowsphone.wordpress.org/
The app works pretty much as you’d expect, providing support for both WordPress.com and self-hosted blogs. Features also include Add, edit, publish new Posts and Pages, as well as managing comments.
Update
I found a pretty serious issue with posts generated from the WP7 WordPress app. Posts created don’t structure the post URL correctly, resulting in ‘Page cannot be found’ message.
