Second, any serious observer of the programming languages would conclude that Odin is in the top 2-3 contenders for the long-term replacement of C. Even if it never attains the goal of supplanting C, I'd argue its historical importance (within its field) is already on par with Betamax or HD-DVD (adjusted for time inflation).
Finally the field of programmers who are able to work on programming languages they made as their full-time profession is extremely rarified, maybe 10-20 individuals at any given time. It is the ultimate measure of having made it -- what we all dream of. At that point you're practically royalty to programmers, and many will know you by name. That is the level of fame (for there is no other accurate word for it) that gingerbill has attained in this community. This dude is a hall-of-famer. Already. Without a single story written about him in a newspaper!
Wikipedia has an interesting problem. How do you build a large corpus of generally true information? Their solution is to offload the work of verification to journalists and academics, who are held liable for their statements by the institutions they work within. This is why wikipedia is a tertiary source. Primary sources originate some piece of information, secondary sources investigate and verify those primary sources (verify being "they said that" not "it really happened"), and tertiary sources aggregate trusted secondary sources. All of the people in the twitter thread (excluding Jimmy himself, of course) seem completely unaware in this system, and while I too would be interested in more "modern" approaches, don't seem to have thought about this problem at all.
Journalism and academia are both on the back foot these days, and it seems unlikely that we will see a big resurgence in funding for either. Without them, I don't see how wikipedia can continue to outsource the problem of verification.
