There are probably a bunch of people behind the scenes, and they deserve lots of credit too. But there is something incredible about being able to post a dozen moderation comments every day for years without ever being so mistaken as to provoke community backlash. It would be really easy for them to offer an offhand opinion, or just make a bad call, and suddenly have people up in arms about it.
They're also some of the most humble people. Both of them have done some really amazing work and have cool hobbies. But I've sort of had to pry that info out of them over years.
http://github.com/gruseom/numen - Dan's project. JS REPL for emacs. It took another four years for anyone to even come close (https://github.com/NicolasPetton/Indium) as far as I know.
https://github.com/sctb/lumen - Scott's project. A self-hosted Lisp that compiles and runs in both JS and Lua. The whole codebase recompiles in about one second flat when using LuaJIT.
But like, that's maybe 5% of the cool stuff they've done. There's just no outward sign -- they don't bother with blog posts or any kind of self-promotion.
So yes, all hail the kings of lisp.
