I like the idea behind this post.
That said, in general, code sucks as a medium for informal reasoning (the kind of reasoning where you try to understand something's behaviour by observing it). On top of that, our tools (text editors, CLI programs, version control systems) are heavily code oriented which makes changing the status quo pretty hard.
The best we can achieve is either:
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
