…which you seem to be interpreting as something ominous. Why?
To me, “social web” encompasses any social networking apps or protocols built on top of the web. As opposed to, say, building social apps on top of email protocols (Delta.chat, Mr Privacy), or XMPP (Movim, Libervia), or blockchains. In that sense, the fediverse is a subset of the social web, which I agree mostly overlaps with the Activity-verse right now. But it didn’t in the past, when it was OStatus, then OStatus+AP+Diaspora+Zot. Similarly, it may not in the future (on that specific point I agree with @stevebate and others, while still disagreeing on the nature of the fediverse).
This forum has always been much broader than any one protocol, and given the name, I see no reason to be exclusive of discussions about social web protocols and projects that are currently outside the fediverse (as I define it anyway). One example of the benefits of a broader scope is the way that discussions here about Solid may have played a role in the genesis of projects like ActivityPods.org.
You seem to have interpreted my if/then statement as a comment on what you’re “supposed” to do, which is entirely your business. SWF appears to have a myopic focus on AP uber alles. So if you want a forum limited to AP implementation discussion only, then SWF seems like a logical host for it. But I don’t think that’s actually what you want. So the idea of embracing a “social web” mission for SocialHub isn’t the threat you seem to be interpreting it as.
Perhaps you perceive that I’ve somehow voted for the SWF to take over SocialHub. If so, I suggest you read my comments again. Because I’m not proposing that, and I would oppose it if anyone was (to be clear, I don’t think anyone is). Because I see all institutions in the fediverse governance layer as peers - just as servers in the fediverse are peers - and that includes SWF and SocialHub. I don’t think either needs to be in charge of the other.
That’s technically correct, but not socially correct. SocialHub began as a Discourse instance on its own domain (there’s threads here about its history). You set up this new Discourse instance as a continuation of the same community, when the person who set up that instance and controlled the old domain name went AWOL. Seems we are more or less back in the same situation with the domain name 
But fortunately we still have you here as an active and highly valued part of the community.
