Nah, it's simply defeatist to assume that ratio is inescapable. On big enough scales? Sure, it'll probably fall around those percentages. But in small communities like we have on Lemmy, there's absolutely no reason only one person in a community of <100 should be expected to provide 100% of the posts or comments. We can and should do better than that, and the best way to turn those 90% lurkers into posters is too encourage engagement and reward it with our own. Will it work for every community on Lemmy? No. But there's no reason not to encourage it. It could only help.
