What advice in particular do you consider bad?  I would be happy to submit some changes to the wiki page for anything that's wrong.

I think it would be great to have a reviewed version in the documentation directly, but I think the world needs a little more experience with Python 3 before it could be done well.  In the meantime, I think it's important to get the discussion moving towards finding a set of best practices.  Raising the visibility of the wiki page seems like a great way to encourage participation and to get things moving forward.

Right now, there's no sense of best practices in porting to Python 3, and it's leaving people with the impression that it's too hard and not worth it.
