It is very US politics heavy. And for many people, that is understandably tedious.
We also don't have a large enough user base to fill out the niche communities, which is creating a lot of little voids that feels like one big void.
IMO, a very noticeable percentage of our users are also arrogant jerks. The kind of users who only reply with snark or criticism, and never add anything positive. You look at their history, and its just comment after comment crapping on others. I have blocked several of these sniping assholes.
The jerks aren't surprising. Guessing many are jerks who got banned over on reddit, so they feel like Dennis Reynolds unleashed over here. A crowd like that can scare people off, though. Social media has a known problem of filtering assholes in instead of out.
Fortunately, there are enough decent people that I still have hope that Lemmy is not a lost cause. It's slowly growing, and some of the new people are pitching in and posting useful / interesting things. Reddit will continue to get worse with its unhinged greed and exploitation. So I hope for future influxes of more people.
