I like Livejournal, it gives me a chance to vent, especially when uncomfortable. That said, it is VENTING. This means that when i complain about someone, I'm usually exaggerating. So if someone is reading this and thinking "Oh god she's mad at me she hates me." it is highly likely that only the first one of those is true. The good thing about venting is it helps me figure out which of my complaints are rational and which are irrational. IF irrational i vent, feel better and forget about it, if rational, i vent feel better and then adress the issue and feel even better. Basically what i'm saying is, if your name appears here try not to take offence and certainly don't feel worried till I actually talk to you about the issue in real life.
Other stuff that I use my livejournal for is memes, counselling my friend when they vent, descriptions of good days so I can look back at them and smile, and reviews of movies.
