I don't think adding a downvote would help. It's what made reddit a crazy echo chamber of the same ideas and thoughts regurgitated again and again. That's why I mentioned above that stacking sats on a post should not dictate the position of a post in the discussion and the default post sorting should be by most recent activity.
yeah that's true, can definitely see that. doesn't matter if it's upvotes only or both, the end result is echo chamber type situation.
I like that idea a lot of the default sorting, as long as there's still other options to sort by. so the default is nothing more than a timeline, and if you want to see the "popular" thoughts you can. kinda like the latest tweets vs regular timeline on twitter.
