Bill talked about Drivel, a GNOME application for posting to your blog. I tried the current version in Ubuntu but was confused when it only appeared to support LiveJournal. I caught Bill on IRC and found out he had to built the latest version of source to get it to work with his blog.
Get your Drivel 2.0.1 .deb (tested for Breezy) here. The official version of the latest Drivel should hit Breezy at the next sync but this will work in the meantime. Note that Drivel doesn’t have an explicit option for WordPress. Just choose Moveable Type and point it to http://your.blog.com/xmlrpc.php
