It’s super new still and the dev is working on getting better instructions up on how to spin up an instance. After that they’ll start popping up.

There will be. The install instructions just need to be polished up, and the tires need to be kicked.

I can’t get the docker image to build, for instance.

Whaaat? So confusing!

I think they mean other fediverse clients, like any mastodon instance, any calckey instance, etc. (not sure if there are more that work currently). It will just show communities as an account where all the posts in the “subreddit” look like tweets and the comments are replies. It’s pretty neat and gives us a glimpse of a world where you can comment on a reddit post / reply to a comment from a twitter account/ui.

Sorry, my bad. I meant like Calckey/Mastodon (Twitter), Friendica (FB), Pixelfed (IG), Peertube (YT), etc. Some would be easier than others though.

Friendica, Calckey, stuff like that
