Which thread? I'm casual, I don't have time or energy to keep a good ratio. I seed plenty, but it seems like private trackers, for all their benefits, would also be a chore. I've looked into them before but never got past needing an invite.
At this point in my life I'm not concerned about the highest bitrate. I use yify for all my movies, and 1337x for TV shows, grab them in full seasons as I need them.
I'm open to new ideas, though, if it's not too hard to get started.
