If you haven't already, make sure you check out George's blogging apps for theSpoke.  There's a Windows Mobile version (for Pocket PCs and Smartphones) as well as a client version.  They work with theSpoke and allow you to update your blog directly from a client app.  He's also posted the code for both apps, so if you want to play with them, extend them, or see how they work with theSpoke, I encourage you to do so.

Also, stay tuned for cool apps from Luke (who's writing an Outlook plugin for theSpoke) as well as Adam and Robert, who have written Spokester, another client blogging app that's super cool.
