I won't be returning to Reddit, but I'm not sure about staying here either currently.
A fair portion of the communities I followed on Reddit were rather niche, so it might be a bit before similar communities pop up here. I'm also not completely sold on the fediverse concept, and there's a strong focus on Reddit hate here rather than actual new content.
On the other hand, I think it has a lot of promise, and the 3rd party app I used for Reddit is also coming here, so I think it has a lot of potential. I just hope Lemmy comes into its own eventually.
That'd be Sync. It's by the same developer, with the same icon and layout and everything. I think it's just a different app. There's a community for it at [email protected] (assuming I've linked that correctly).
I think a bunch more apps are making it here too, but that was the one I used.
