I mean Lemmy shares a lot of the same issues as Reddit even if it’s decentralized. I think Lemmy as a technology is better than Reddit because it’s more privacy focused, but most people don’t care about any of this. People put up with Reddit’s shortcomings because it has a massive community that is always active and fills every niche. Reddit’s daily active userbase is over 73 million. That’s hard to replicate in general, but I don’t see Lemmy getting anywhere near that mainstream. I see it as a more stable and active version of Voat, but still a niche platform nonetheless.
I think a big issue with Lemmy is that I think there’s a lot of people who become disillusioned with it, just like how a lot of users became disillusioned with Reddit. When users join this site, they’ll immediately notice that there’s nothing outside of extremist politics, privacy focused tech talk, and shitposting. Unless they’re interested in those topics specifically, a lot of people would rather either just go back to Reddit where there are active communities outside of these topics or find another, more active platform. A lot of people thought that Voat was going to rival Reddit when launched, but it ended up being a niche hub for extremist politics, tech talk, and shitposting until it shutdown. Now Lemmy is definitely better than Voat in every aspect, but I’m not sure how it can over come that big hump that will allow to appeal to general public
