I am tech literate and even for me the choice of “which instance to register on” delayed my Lemmy sign up for 2 weeks. I eventually just signed up on 3 of them but now I have 3 different accounts each with their own set of subscriptions and favorites.
Aside from that, the Lemmy UI is a usability disaster and needs an overhaul. I’ve been thinking of giving that a try but I already have other projects that are taking up all my free time at the moment.
