To me it's a feature and not a problem to have less people. I had more online human interaction in lemmy than I had anywhere else (except maybe facebook in early times). Look at Reddit now, good luck interacting with real genuine people. Everyone is shilling something and nobody is honest, plus the low quality posts count growing.
I saw some studies a few years ago on how people are less interested in traditional social media and more interested in instant messaging 1to1 and small group chats. Also something about how group chats become dead after they exceed a couple hundred members.
Just to say, I am more happy with the way things are in lemmy. I appreciate all aspects of Lemmy really.
I remember the millionaire who wanted to prove that he could rebuild his wealth if he started from scratch again. He cheated a little bit because he used his friend apartment for free.
Fast forward, he gave up after a couple of months and understood what the rest of us knew for ages.
Wealthy people are delusional and no amount of reasoning will work with them.
