The idea that community votes will result in the best content floating to the top is flawed, because what happens is the most popular content gets upvoted and not necessarily the most insightful or pertinent. This effect is magnified as the network or communities grow and welcome more a more general audience. The most prominent commentary is often useless jokes, memes, reactions etc. Slashdot, HN, lobsters have similar flaws with different strategies to overcome them.

Yep - true I do see things being easily gamed but then also lemmyverse does seem to be a personal favourite now - i hope things don't change down the line.
