What particularly made you quit?
I liked moderating when we had admin support. We no longer have admin support, so I really didn't feel like moderating anymore. My "syncretic" account was pretty much just for creating subreddits, submitting content to those subreddits, and moderating those subreddits. I felt a responsibility to those subreddits because I had created them or at the very least I was a senior mod. I'll still use reddit, I just don't care about it anymore, I'm not emotionally invested in it anymore, and I don't trust a single word that comes out of any admin's mouth.
Several events in the last several months have made me realize that I am an unpaid volunteer for a corporation that really doesn't care about quality over quantity. They want pageviews, they want internet power. Look what they did when SOPA and PIPA threaten their existence. Shut down the entire website in protest and start the ball rolling for dozens of other sites to do so as well. What do they do when Gawker publicly outs one of the most prolific moderators and community builders on the site? They banned the article site-wide for doxing (as they should have), then unbanned a few hours later, then they said absolutely nothing for several days while the mods scrambled to figure out what to do (do we remove it, do we approve it, do we boycott Gawker Media?), and then instead of a public statement in /r/announcements (like, oh, I don't know, a condemnation of Gawker), they make some stupid post in the mod back room about how this is a "complicated issue" etc etc.
What would they have done if some Mens Rights blog outed the identity of someone from the LGBT community? Oh wait, that happened, and they manually went into the subreddit to remove the post, against the wishes of a moderator. Yes, that was the right thing to do, but it just shows you how they enforce the rules however they please, and only when they aren't going to get bad press as a result.
Are you reading your "omg syncretic quit" threads?
