Do you post long, emotional revelations on your journal? Sometimes. Depends on my mood. Sometimes they're friends-only, sometimes not.
Do you expect responses? Sometimes I do. Sometimes I need responses and don't get them. Sometimes I think that the things I write are for sure going to provoke comments, and don't... sometimes the shortest, dumbest things provoke a billion comments.
Do you comment on other people's long, emotional posts? Yes. Some of those posts are just begging for it. It's long been my assigned duty on this planet to bring joy to other people's lives, joy and hope and happiness and laughter, in any way I could. I've known this ever since I was fourteen, and I've been figuring out how best to do this ever since. Commenting on LJ's one way.
Does it make you uncomfortable to learn about despair, abuse, rape, betrayal, misery and decay? Infuriated, perhaps. Saddened. Angry. Upset that things like this are happening to such beautiful people out in the world.
Or does it just make you uncomfortable to make comments about other people's despair, abuse, rape, betrayal, misery and decay? Sometimes there's nothing you can say that won't sound wrong or dumb when written out in black and white, or whatever colors your monitor and programs are set for. Sometimes you have to fall back on one of the stupid-ass little comments tossed into the post that weren't important at all, and talk about those so that at least something will be spoken of. .... Sometimes you just want to leave a post to say "I was here. I read this. I don't know what to say." There should be an LJ-specific word or tag for that: lj-kilroy?
Is being added to a friends list an automatic invitation to comment on other people's despair, abuse, rape, betrayal, misery and decay? Myself, I'd say it's polite to lurk for a while and make smaller comments so you can get to know each other a bit before making intrusive comments. Then, who am I to prate about manners?
Can you truly know someone through their live journal? That depends on what you see of them and what of themselves they choose to show. Some people can't hide anything no matter how full of bull they stuff their journals; you know them very well. Some people tell the truth and a good approximation of the whole truth. Some people hide almost everything but reveal more by their word choice and more. Some people, you'll never know. Same with reading paper diaries.
Is an LJ persona closer to one's true self or farther away? Closer than what? Than knowing the person IRL? Mine probably is, if you're speaking of how well some people know me, and how much I hide. But if you're speaking of how well my parents or biological sister or heartsister knows me, there's no way my limited words here can convey that kind of depth. If you're talking about how much my friend Darkside knows me, I'd say that LJ presents a far more complete picture of me than he's seen. I post in every mood; he's never seen me in a few emotions that he will probably never see me in.
