I just don't think I'll ever "grow out of" LiveJournal. I mean, aside from the ludicrousness of abandoning a permanent account, this seems like a fantastic place to archive one's life chronicles. If this existed when I was a kid I would've loved it and I'd browse back even now to read some of my old entries. (I think I still have some of my written diaries stored away somewhere...)
I guess it helps that I'm far more comfortable sitting at a keyboard than sitting in a room full of people. :P I'm naturally bent towards this medium.
What about you? Do you think you'll still be using LiveJournal in 5 years?
