What in the world is the author talking about? I went there to discuss local issues (r/stlouis), look at cool maps (r/MapPorn), find credit card deals (r/churning), and shit-talk sports (r/baseball and r/hockey).
I've been on reddit for almost 13 years. I keep seeing hot takes about what it supposedly is (or was), but they never match my experience.
You can find porn and nazis on the internet, yes, but it would be a profound mistake to describe the internet as a tool for finding porn and nazis. So it is with reddit, too.
