I invite ALL federation developers to hop into #social on irc.w3.org for conversations around the social Web. It's where a few discussions on #ActivityPub discussions occur.
I know that we have http://socialhub.network/ for this as well and I encourage the devs to use these places in conjunction to this one for conversations for historical and open discussion reasons.
@jalcine I had issues getting onto the IRC server.. Is there an IP block or something?
@emacsen I wouldn't know. Perhaps check https://www.w3.org/Project/IRC/
emacsen.net is one server in the network
