I like what I'm reading here.
The author is terrifyingly young: http://maxsi.org/
I don't feel like checking it now but Linus was pretty young too when he released his kernel.
Maybe he does not want to deal with reviewing shitty PRs and comment noise and feature requests? (As far as I know you still cannot disable PRs).
This is already a large and no doubt time consuming project as it is, and not everybody likes to be a "community manager" more than they like to code.
editor is use-able. python on there, Asteroids is working fine, too. Will be following the progress. Well done!
Now someone just need to use Rust to build yet another kernel? :-)
But compared to other hobby/DIY operating systems, this seems to be a fairly complete system with a real userspace and ports of real applications. Which makes it much more finished than 99% of similar projects.
