It’s pretty dead, a lot of pods has closed down last year and it continues to shrink, they could maybe reverse the process by supporting ActivityPub or other additional protocol, but they have refused, and diaspora* protocol hasn’t gained any additional traction, sooo…
Won’t happen.
Around December 29th, multiple big diaspora* pods shut down. According to one source, diaspora* lost over half of its users within three days. On January 25th, diasp.org, one of the biggest pods, will meet its end.
Also, if anything, Friendica (plus Hubzilla plus Socialhome) will suck the rest of life out of diaspora*. diaspora* users will move there from their own dying pods to stay in contact both with their friends who still hold out on diaspora* and with their friends who have moved on to something that uses ActivityPub. And the former will become fewer and fewer as more and more pods shut down.
