👆 is not a criticism, rather an observation based on very shallow, but careful analysis of the ratio of boosts per post (appropriating somebody's fancy content for one's own) vs. likes/fav-stars (sending 👍 to the original author).
On the upside, the current design leads to the only meaningful mode of interaction which is 1-to-1 dialogue in DM.
