Wikipedia, OpenStreetMap, the Internet Archive, Mastadon/ActivityPub, Peertube, git and company, and something like but more open than StackOverflow (which feels like it should be a part of Wikipedia in some way, shape, or form). NNTP is suggested, but feels like it's been superseded by superior mechanisms (although there's much work to be done as part of the Distributed Web movement [1] [2] [3], which would also be applicable).

TLDR Open abstractions on top of open data trivially and rapidly distributed.

Maybe a separate project of the Wikimedia foundation, sure.

https://codidact.com/ and https://topanswers.xyz/ are two SO alternatives.

I keep dreaming of someday seeing a resurrected Usenet, but I know it will never be anything but a dream.

When humans finally make settlements on Mars and venture into space, decentralized web will be resurrected, as anything else would be utterly unusable with the interplanetary latencies.

Maybe not. You're definitely not the only one who wants something like that.

There are definitely still some active text groups on usenet. Either people that never left or folks returning/visiting for the first time, the potential is there.

Years ago some folks broke off from Slashdot and started posting to comp.misc. They're still going today

There seem to be quite some people in here feeling the same about USENET.

I had a quick look around, and the tools aren't trivial to set up. If someone who has experience with NNTP servers could bundle things as nice Debian packages with easy setup then that may help spread it again.

Spam can be reduced by using moderation, I wonder if there are new ideas around for countering spam in non-moderated groups?

Turns out old Usenet content is particularly hard to find nowadays...
