As per above, I don't really mind what you do with your own LJ - especially since you have an excuse in being so busy. It's a nice way to get the dispatches from the front, so to speak. :)

But the random tweeting does tend to feel a little impersonal, or at least directed to persons who rather pointedly aren't the majority of the readers. Which I can see being a little awkward on a community-based blogsite.
