Tbf I think the way its federation works is inherently incompatible.

I could be entirely wrong though

Don’t all mastodon accounts have RSS feeds?

Some people want some sort of suggestion system. I figure as long as it’s an opt-in choice, why not? Gives people what they want and makes the ecosystem more enticing. And at least it’s an algorithm that’s transparent rather than one controlled by a large corporation.

The companies he took over after they were were founded?

If a mastodon user mentions (@) a community, they’ll post there. They can also reply to comments on Lemmy and you’ll see it. Unfortunately I don’t think Lemmy has a way to see regular mastodon accounts/comments right now other than that.
