"if anyone needs any help with writing documentation, I'm more than
happy to lend a hand"

I don't think you will find many people who will respond to this - 
mostly developers are too lazy to write documentation.

BUT what may be VERY useful is if you start to collect which projects 
need help, then point this out, and then offer help.

If some projects respond and the documentation improves, this will help 
everyone.

My personal pet peeve:

Ruby stdlib documentation. It needs improvement.

Python guys have better documentation!!!
