At least on Reddit there was some leveling of downvotes built into the algorithm. This site is making it seem like any slight disagreement leads to downvotes thus encouraging more echo chambers. Maybe it’s the communities I’m commenting on?
It’s already an echo chamber. That’s just how human interaction is. People aren’t going to share unpopular opinions just to be argued with and downvoted. It’s not worth it.
Take the recent question about religion. No way am I going to answer that, because I’m not atheist and I know how non-atheists are treated online.
