No.

But sort of.

We need to /s/DecentralizeAllThings and /s/FederateAllMedia.

DECENTRALIZE to spread out and to never be taken down together.

FEDERATE to interact "centrally" in a contiguous cooperative manner, mirroring all social media, media, and activity - despite being on different platforms.

In this way, instead of the center being a single site (corporate or not), the "center" is wherever you are, like being on the Internet.

IMO, MediaWiki might be among the best options out there. It's exceptionally supported, very robust, easy to install, and of course it could manage all the media you can throw at it.

MediaWiki would also be a terrific forum base, but I see 3 problems with embracing MediaWiki for Reddit-clone communities. 1) The site layout/format would need an overhaul to redesign it to appear and function like a Reddit-type forum, including permissions and voting/points(/and crypto?) systems. 2) Federating. 3) A minor issue - the markdown code is different, though easy enough to adapt to - plus they have formatting aids. If someone or some folks could address those two major issues I'm certain they'd have a huge hit on their hands and many sites might migrate.

Side note:
/u/d3rr, I've considered creating /s/Fediverse for some time, but have hesitated as I am no expert, don't keep dialed in, don't have sources for Fediverse news, and figure it's redundant to #DecentralizeAllThings (which I now need to make clearly distinct from AltTech and Crypto). Now that I just came up with a new #FederateAllMedia, I wonder if it's better and/or more compelling - or if making a new sub is even a good idea at all. Thoughts?
