edit: oops. dont hit return like you would in a real post or it will send if you have "send on return" set in your adium client lol.
I set up custom triggers like #tweets for status/microblog and #blog for updating to my LJ. That's as far as I've messed with it so far, aside from posting via website and posting via AIM network. Too bad there is no desktop client for it but I suppose an AIM client will do, especially now that I have AIM for my Tilt phone. I can always email to it too.
