Ask HN: Does anyone want to build a programming language reference with me?

I have noticed that there is no structured central hub for referencing programming languages. How to implement certain things in them, what terminology means etc.

Stackoverflow has a lot of this information but not in a structured way and the quality of answers vary widely.

My idea would be to make a central service, which is completely free, which people contribute to (based on guidelines) to make referencing everything that much easier

Any thoughts/help would be greatly appreciated
