Tried it last few days and I kind of like it a lot.

That is the logic most people confuse with socially-focused spaces like the fediverse ecosystem. The point is not to create monopolies but to have a diverse information system so no one node controls the flows. Co-existence is the word. The tough bit is to create a space big enough to create healthy information flow without being too big as to monopolize the neighborhood.

Precisely. Sharing your finds and commenting on what others have found is the ideal situation. When only 1% post content, and slightly more comment, it is easy to game the system - like Reddit and these other “socials”. Lemmy’s robustness will be a function of its people.
