As stated by Dave to me in a email:
"This looks awesome man. Pure awesome. I love that you flipped the queries to actually optimize for a true mobile first implementation and extending it to 1200px is a great idea. I honestly think you should fork Skeleton on Github and create this as your own repo and I would be happy to link it up on the docs."
So I forked the original skeleton and here it is Responsivekit.
I added also responsive tables to make the boilerplate as complete as possible.
See it in action on http://responsivekit.com
web2py is the only framewrok to be responsive from the ground up, check the appropriate repo here web2py-responsivekit.
