What make you join with site?

Earlier this year I felt the need to find an outlet to post things on an anon forum.. I first found a site called Quickrant, but that didn't really have the interaction element and people were mostly posting weird stuff. Then I found this site Muttr, that site was pretty good, you could post anonymously or log in and have a user handle. I was on that for a few months and it was addicting, lots of interaction, but the user base was mostly teenagers posting their teenage angsty crap. The feed would be flooded with people saying they wanted to kill themselves every single day, it got really annoying. The people on that site were just too immature to have any meaningful exchange with. Then that site got shut down.. so now I'm here. I've been on here for a month or 2, it's okay I guess.
