I'll probably get hate, but the content just isn't there. I tried using Lemmy as my main, but most of the communities I'd follow on Reddit just weren't on here, and if they were, they would have a couple hundred of subscribers at most, and there would be 7 different versions of the same community on different instances with no way to measure quality at first glance. Lemmy thrives for geeky hobbies that surround the FOSS space that gave birth to it, so communities like Linux or Unixporn have a strong enough presence, but for pretty much anything else it's just not there yet. Is this a negative feedback loop? Yes, but there isn't much to be done about it until shit REALLY hits the fan
PD: As an added, Lemmy can get incredibly circle-jerky at times, even more so than Reddit already is. Like seriously at times 90% of the content on my feed is just shitting on Reddit plebs
Give it 2 days and chances are someone has already published a PKGBUILD in the AUR
