#Fediverse's instances with #ActivityPub support (#Mastodon, #Pleroma, #Epicyon) can be seen as a decentralised replacement for #Twitter. They have a similar functionality, and we can say to our friends that they can use ActivityPub instances in a way similar to the one of Twitter. If the all users of Twitter would register at ActivityPub instances, it would be possible to forget about Twitter the same day.

I registered today at #diaspora* instance, and I cannot say diaspora* is a replacement for #Facebook. Yes, it allows me to have a somewhat more detailed user profile than in Twitter and ActivityPub. But even if all your mates from school, army, institute, work etc. would be registered at diaspora*, you would not have remedies which would let you to find your mates and would let them to find you. If I would say to someone that diaspora* can be used in a way similar to the one of Facebook, I would be a liar.

So, does exist a decentralised #social network with a functionality similar to the one of Facebook?
