All with Xpostulate.
Earlier today I added DW-specific tags, and some additional html insertion features, as well.
ALSO: I initiated a project for Xpostulate on googlecode this morning.
There's still work to be done, of course...Plenty of work...
All the same, considering I started this project less than a week ago, I'm fairly satisifed!
I have already released a viable, crossposting blogging and microblogging client.
Sometimes I'm so awesome, I can't stand myself...
