Quite like it. Jerboa is usable despite its early development state.
I miss and probably will continue to miss some of the smaller niche communities, which are really only viable on huge servers/networks. Notably /flying and /NetBSD. There probably aren't enough active users to create thriving communities on both reddit and lemmy. Although /r/flying participates in the blackout, I expect most redditors there will stay. I used the site on desktop most of the time, too, and I don't see myself cutting all ties, either.
So, ambivalent, I'd say. I'll see what the mobile app situation will be in a few weeks; Infinity has worked well for me.
But that's the whole point: the is no centralised organisation. Which is the reason most of us are here. Duplication is just an unavoidable side-effect.
And it's not as if reddit were immune from that. Lots of similarly named subreddits on the same topic.
So that's not something that is "to be done". (Unless you meant TBH: to be honest.)
