Perhaps there is a solution that will resolve the legitimate concerns about post quality while reconciling the (arguably regrettable) fact that meme'ing may in fact be "what the people want."
Or, since the Powers That Be have more choice in the matter, they could arbitrarily put some fix in to limit the dmania-style shitpost-mining. If, that is, they prefer quality content over "what the people [seem to] want."
Stake is always going to prefer whatever raises the value of stake most. We'll need to cater to that reality.
