Sadly, no. Just not enough content on Lemmy, yet.
As somebody who just uses the mobile site on Firefox, I didn’t really feel affected by the API changes (besides the fact that Reddit once again showed their ugly face). All the subs I care about feel unchanged.
Yes. I see a lot of comments on Reddit like “I tried Lemmy, but you have to sign up for every instance”, because it’s so opaque how you can subscribe to different instances. Personally, I copy the “handle”, add it to my URL manually, then subscribe. But this is nothing any mainstream user would do.
I like it! Main issue for me is that there is not enough content on my hobbies, and “all” content is mostly filled with reddit-this and lemmy-that (or now threads) stuff, which is annoying because I don’t want to talk more about the platform than actually using it. But I hope this will change with some time.
I use only the browser, UX and UI is pretty straight forward, but subscribing to communities of other instances is really weird. I need to copy the “handle” (i.e. !lemmy_support@lemmy.ml), and add it manually to my instance domain (i.e. lemmy.world/c/lemmy_support@lemmy.ml), and then I subscribe to it. I don’t know if there are other ways (besides finding new communities via “all”).
I’m not into the technicals of lemmy or the fediverse, but I guess this is not easily solvable, as an instance doesn’t know that I am the user of another instance.
Arts (Printmaking, Graffiti, sculpture, calligraphy, typography, design), and all the SFW porn subs.
Also, I’m really amazed that https://lemmy.world/c/sourdough is already quite active.
Overall, maybe. But in my niche subs not.
