I'm on it, but I don't post a lot. A good portion of the community sucks for various reasons, but if you take the time to subscribe to subreddits that interest you and get rid of a good majority of the default subs, you can actually have a decent time on the site.

I basically joined because I am a Game Grumps fan, and their subreddit is one of the better means to see all the fan stuff in one place. Again, the community can be way too much, but it's worth it because the crew is fairly active on that part of the internet.

Anyway, as time went on, I explored other subs and before I knew it, I customized my account to make it a great anti-boredom tool.
