What's a safe site meant for ranting where you can edit or delete posts?

[Elisha]

I just really need to vent about something but I'd rather not bother my friends about this because it seems so trivial. At the same time, I realize that I'd be more relaxed about posting something on the Internet knowing that I can edit or delete it. At the same time though, I'd prefer a site that is visited by many every day. I'd also rather not resort to Facebook because I'd like to rant anonymously.
The thing is that I want feedback from a third party, otherwise it does nothing for me.
