I first joined Lemmy back during the big Reddit exodus of last year. I like many others wanted an alternative to Reddit, and I thought that this might've been the one. I made two accounts, one on lemmy.world and another on sh.itjust.works, in the June of last year that I used on and off for about 4 months.
At first Lemmy was exciting because it was so active. There were so many new users who were enthusiastic about turning this platform into a genuine alternative. There was a communal effort to create and interact with content, and for awhile it worked. Lemmy was truly interesting during the summer of last year. However, this stream of dedicated users started to slowly decline.
A lot of people hoped that if they were active, they would attract and retain more users to this place to the point where the community would foster interest specific communities like Reddit, but that never happened. After a few months, a lot of users lost interest and went back to Reddit where the userbase is so massive that there is an active community for just about anything.
With this reverse exodus back to Reddit, Lemmy ended up with the same groups that were active on it before hand: political extremists, tech nerds, privacy enthusiasts, and shitposters. To be fair, all these groups are larger now than they were a year ago, but that's all this platform has to offer. If you're into any of these things and primarly these things then Lemmy can be a good alternative to Reddit, but for the general masses? Lemmy is just not good.
For example, a NBA post on the NBA subreddit can get you thousands of interactions in a couple of hours. An NBA post on here will maybe get you a dozen over the course of a couple of days. The only content that will gain any traction here are tech news, political propaganda, and maybe some memes. I don't see this changing any time soon. Even if Reddit implodes, I still think Lemmy will remain a niche platform. I think this evident by the fact that this platform hasn't really progressed in a year.
Lemmy is missing:
You know you're right, we're nothing like reddit!!
Actually I have heard of some insane mods
There are some power tripping mods, thankfully there are only a few
