Trying out #Lemmy. First impressions are that it's a bit intimidating.
Much like moving from Twitter to #Mastodon, #Pleroma, #CalcKey, #Akkoma, or others, Lemmy intially appears rather sparse compared to #Reddit (or at least the instance I joined does). As with the rest of the #Fediverse, you have to seek out communities to join. However, the decentralisation of Lemmy introduces some friction there which isn't present on Reddit, and I haven't really experienced it on Mastodon either.
I've been really wondering about that but haven't had time to sit down and look into how Lemmy interfaces with the rest of the ActivityPub world.
My quick glance is at it looks like Lemmy is effectively a walled garden even though it uses standard protocols, which would be disappointing.
