The trick to post-2008 Reddit is to be very, very judicious about which sub-reddits you subscribe to. There are still quite a few gems. I've flirted with abandoning ship since the early 2009 hockey stick growth, but found peace by continuously weeding out sub-reddits that had gone bad. It's kind of like pruning a bonzai tree.
This is my go-to answer to anyone who complains about pun threads and whatnot. If you're running into that stuff, you're on the wrong subreddits. My discussions there are perfectly enjoyable since removing r/atheism, r/pics, r/reddit.com, etc.
