It's been limping for a while, but the momentum was huge to begin with. The niche subreddits still had good participation, not great, but good enough. These latest shenanigans might be the final tipping point, though.
I'm a 12 year too and just switched over when they blocked Boost last week (so, right before this Luigi stuff). I have to say, after a little learning curve, I like this experience a lot better (still on Boost, BTW). Keep on tanking, Reddit; the more users that jump ship, the better. I'm planning on backing up my post/comment history before I delete my account, but otherwise I won't be looking back.
