I would love to hear some opinions on this proposal for Haddock:
Proposal
Add the cabal homepage attribute as rel=canonical to the contents page of Haddocks.
Discussion
Where should a Google search for a package take you?
- To the package Hackage?
- To the project homepage (most often the Github repo)?
If the answer is (2), (which is my opinion, since homepges tend to contain fuller descriptions and point to further resources), then adding a canonical tag should search engines pick this up.
Comments are probably best off in the repo.
