I get what you're saying, but this seems like one of those things where everybody agrees that 90% of the internet is shit, but they can't agree on which 90%. Which is the difference btwn your description being total pathology (for me, this would be a btc maxi echo chamber screaming the catechisms at each other) and being the sign that things are working out great (a bunch of people who say interesting things being perpetually rewarded for saying interesting things).
Territories experimenting with their own reward rules will just make it the wild west. Those with the best reward incentives will get the most traffic forcing other territories to follow suit. It's another race to the bottom.
Oh wow -- for me, that sounds like a race to the top! An ecosystem of innovation.
