One of the reasons I migrated my site to WordPress was all of Dave Winer's evangelism. One of the things Dave has done is an external editor for WordPress called WordLand. I had tested it out briefly with a test site on WordPress.com, but now that my main site is on WordPress, I'll see how it works. This post, was written with WordLand. I wasn't sure if it worked with self-hosted apps, but I guess because my site is linked up with WordPress.com via Jetpack, it just works.
