@feditips one of the problems is that it's never quite clear what comes over from one service to the other. I can see bookwyrm reviews on mastodon, but I only can see comments on my reviews. Same with lemmy for example. And pixelfed. I still don't get what funkwhale is supposed to do.
Friendica can also share stuff that's not visible by mastodon (rss articles, or diaspora posts).

It's all a bit unclear how this is all supposed to work together.
