The #KISS path is to simply bridge them all and let them cooperate, as they are all a part of the #openweb family.
The more complex and messy path is that some of them might not want to do this... OK now we get to the part where piss is likely signal rather than noise. Let's draw a line, (a date is good) if they don't bridge, we let loose the pee, liquid trickling in will short out their servers.
@rabble it had better #UX and the @Gargron running it was an effective communicator at #KISS and built it out as a #4opens project alongside a healthy (white) lie about security and privacy. The rest of the projects lacked these things - Pleroma the obverse compaine was ripped apart by the #geekproblem then embraced by the right-wing. #Peertube was stuck in a good but very closed development for years. #Pixelfed is a little brother project to mastodon.
