This is sort of a perfectionist perspective. Search engines use the same “gamification” and suffer the same problems you’re “predicting” but that doesn’t mean you don’t use search. It does mean it’s an arms race between the engine and the abusers. Weighting the agents instead of the content is no different than a popularity contest and is essentially an “appeal to authority” (or a lot like cancel culture). Just because someone has weird opinions about X doesn’t mean they can’t be brilliant about Y. If you ranked the content then their X content can sink and their Y content can rise. The problem with Twitter, etc. is that their incentives are not as aligned with their users’ goals as we would like. Probably the best part about blogging was that it wasn’t centralized and so wasn’t subject to one person’s definition of what those trade-offs should be. But, of course, now we’re trying to discuss fixing one of its weaknesses without losing too many of its strengths.
