I know that the purpose of Lemmy is to be split into instances and stuff to stay independent or whatever, but - imo - if it really wants to become a true alternative for Reddit it needs one place for users to land. Something like “LEMMY.COM” where you can see all instances + all communities, where you can log into your instance, maybe even log into more than one instance at once (let’s be honest, who doesn’t have a separate porn account these days lul)
The thing is, most of us used Reddit until now instead of Lemmy because Reddit did the overall browsing experience a lot better. Yeah it needed the help of third party apps for that, true, but I could just open reddit, look at r/all or my subscribed subreddits and be done with it. Being on Lemmy feels like “oh yeah, this is a great idea, but wow it is very inconvenient to look through this place”
(Btw, I LOVE the lemmy logo!)
The closest thing to that right now is lemmy.directory. It federates with “every” instance.
It won’t ever be like you describe, but there are some talks to add better discoverability features to Lemmy. Once that happens, and you can subscribe to different instances from other instances (i.e. not yours), lemmy.directory will likely end up being a landing page of sorts. Currently you have to subscribe manually.
