I didn't notice much degradation after the 2016 election enshittening. I set to work blocking all the power users and was able to to maintain the post-2016 level of quality right up until I largely quit.

There are two subs I use that have no Lemmy equivalent (one of them probably never will) but otherwise Reddit is just a marginally better StackOverflow for me now.

Also I must admit the Excel subreddit is simply too useful to quit. I'm a damn wizard at this point and these people still surprise me.
