Does federation have a bit of a learning curve? No doubt.
Is Lemmy buggy as heck? Absolutely.
But I don’t think that really justifies a lot of the comments I’m seeing in Reddit alternatives threads that it’s hard to figure out. The front page feed and sort options are very similar to Reddit. Searching for same-instance communities is not too difficult. Posting, commenting, and voting are all quite intuitive. What’s the problem?
There’s a bit of learning curve for sure, but people shouldn’t overthink the federation aspect too much. At least here on Kbin there is plenty of content already.
