I can well imagine someone turning away from a language because the docs felt old or badly styled.
One practical effect of it is people preferring to read articles on other sites rather than consult the docs first. One piece of docs that is greatly explained is the sockets section. The part i am referring to is in the how to section i think. But i don't don't think much people read it first before starting to program. One site which balances aesthetics and great content is the RealPython site.
