Tried your link but, as with the rest, get a 404. Raven doesn't seem to exist any more.
I've worked through the list and, in the interest of providing an update (and saving others similar sleuthing effort), here's what I've found:
* BlogGTK is also dead. No activity of any kind since 9/26/2010.
* RocketPost, also an 'essentially' dead product. Anconia's not supporting it and the reviews, well, let's just say unfriendly is putting it mildly.
* BlogJet, pleasant enough looking app, seems a direct equal to Live Writer. Free to try, but $40. Considering it's equal to WLW...
* BlogDesk - Seems most interesting of the bunch. Installs and configures very easily. Interface text is a bit hard to read (Win 3.1'ish). Unfortunately it's not quite WYSIWYG. Or, at least it's not compatible with what I'm doing in WP. Throws off a lot of spurious characters when opening any of my prior posts.
* ScribeFire's clearly the best of the bunch. Unfortunately it's browser-based. As such it's only partially functional if you're offline. That said, since I'm 'generally' online when writing, I'm going to dig in. What I've found initially is that it's -very- fast interacting with my WP server. As in, never-seen-anything-quite-this-fast-before type interaction while blogging.
