@maegul No, I'm serious. I think those kinds of dead connections are what we got with Lemmy. Federation in theory but no one actually using it because it doesn't meet any needs. The main way for Reddit to be shared on twitter was screenshots and that's probably what would work best between Lemmy and Mastodon as well. Or Tumblr and Mastodon.
I still think blog feeds is more likely to be useful, but that's also because I dislike using RSS readers because I can't deal with many apps.
