Crossposting to social network sites outside of LJ? SOOOOOO not gonna happen. Well, not from me, anyhow. I keep my LJ very separate from my Facebook - they're for very different purposes in my life, and there just isn't anything I can think that I need to crosspost except the occasional news-type article I find. And that would be *me* crossposting *my* journal entry. I won't crosspost anyone else's entries without permission, nor my comments on anyone else's - this is Vegas, baby, and what we write here stays here.
I try to protect my friends. Y'all are awesome, don't ever forget that. :D
