if u havent realized:
lemmy tends to be significantly more appealing/valuable to some niches that have strongly established,enthusiastic, talented userbase (such as tech ppl).
it's a minor satisfaction boost but beneficial. if maybe u dont fullheartedly believe in the lemmy mission(free nonprofit decentralized platform), then it seems, additionaly, less satisfying

to build up other unique /c/'s requires: initiative, light work/time, [and usually..] motivation to post.

i personally [tend to..] only post or comment on things im interested in. sometimes thats only linux and android.

when a site like reddit is ranked top site on the inrernet. everyone can be lazy and contribute once a year and thats still more than enough(when u consider scale). there are also a shitton of negatives to that. but they are ignored and swept under the rug.
