+1 to expanding the introduction.  Do you have a phrasing suggestion?

IIRC it was on python-ideas, and (among other criticisms about licensing, site reliability, etc.) the strongest opinion against adding links was Alexander’s, who reviewed the PyMOTW page for datetime and was not satisfied.  So the discussion ruled out systematic addition of links for all modules, but I think that as usual a core dev is free to add a link to an external resource if they think it is useful.
