Hah, aber mal das /s beiseite, es wäre schon ganz groß wenn es in Deutschland mal wirklich solche großen Langzeitprojekte geben würde. Aber hier wird ja immer eher von Zwölf bis Mittag gedacht.
From a mastodon users point of view a Lemmy user behaves like another Mastodon user. For instance this is what my Lemmy profile looks like from mastodon:
Even though they boost ( e.g. “retweet” ) everything that has been posted to the community. Be it a thread or a new comment.
The big upside of kbin is, that it, as you said, combines micro blogging and news aggregation. While Mastodonusers can interact with lemmy content users on lemmy can only reply to comments posted from Mastodon. We have no real way to send a toot (e.g. “tweet”) to mastodon deliberately.
