I looked closely at the new LJ FB and Twitter functions, and from what I could determine, you can only repost your own comments, so it's the same level of security as before.

Not moving, because a) I'm too lazy, and b) wank'll happen anyways.

According to tests Cleolinda did somehow in the process bits of the entry you are responding to get posted too.

She posted extensively on the experiments she did to see what would happen:

I'm not leaving either. I just got an account to more easily follow those who do. Even though I've been doing more personal posting lately then I usually do I don't expect to ever post stuff THAT personal here. I try to keep my real name out of stuff in case I have a future employer who thinks liking beefcake and slash is grounds for not hiring me but other than that if I don't want half the world to know it then I'm not going to post it here.

Interesting stuff from Cleolinda's corner, and I would hope that LJ is paying attention to the 4500+ negative comments they've received regarding this 'spiffing' new feature.
