Good aside from all the repetitive content. One of the problems with federation, I suppose. Someone sees an article they like and they feel they have to post it on every community related to politics on every instance they can find, for example. Mostly a politics problem, but also memes and gaming and technology. Okay, not mostly a politics problem.
I think the same problem exists in reddit as well. There's a lot of sub with slight variation so the same content will show up again and again because i subbed to multiple of those sub. (eg: holdmybeer and holdmyredbull)
If you use the browser UI, the ui will group all those crosspost together.
I think a good client could solve the repetitive content problem. For example, if a link shows up in more than one community, have it posted once with a divider above it saying where it's been posted.
I've been finding the same and have just started using the filter option in my client lately. It's not ideal but the alternative is that I get bored of seeing it and stop using Lemmy altogether.
I do worry that the repetitive content will drive new users away
