I used LiveJournal frequently, almost daily, since ~age 13 until ~18. I kept a personal diary there. I also participated in various "LiveJournal communities". At the risk of sounding patronizing or something, I see LiveJournal and now Tumblr as wonderful because they give young girls ways to interact with eachother and learn and talk about new interests, ideas etc as well as support eachother emotionally.
I recognize that memory is far from infallible though. If I feel like I can't accurately describe something, I just leave it out. I also do things like write "he talked about ..." instead of writing direct quotes. But generally I feel like since my stories are very obviously meant to be my perception of an event rather than the objective truth this gives me a lot of leeway.
