This is a really solid framework. A couple of humble suggestions:
1. Package up your site itself on github as one of the examples. Mixing up some elements of your base site with some of the landing bits would make for a solid base for a lot of people.
2. Get a compatibility table together stat. To help you out, I did a quick test of both your main site and the landing page. Nothing in depth, just the basics. The following browsers worked properly:
On Windows (8.1 unless noted):
Firefox Stable 34.0.5
Firefox ESR 31.3.0
Opera 26.0.1656.32
Google Chrome Stable 39.0.2171.95
Internet Explorer 11
Internet Explorer 10 (Windows 7)
Internet Explorer 9 (Windows Vista)
On Ubuntu 14.0.4:
Firefox Stable 34.0
Chromium 39.0.2171.65
Google Chrome 39.0.2171.95
On Android 4.4:
Google Chrome 39.0.2171.93 (both landscape and portrait, phone and tablet)*
Firefox 34.0 (both landscape and portrait, phone and tablet)*
* Note that the UI navbar didn't stick on the phone for either browser despite the phone having a 1920x1080 resolution vs the tablet's 1024x768 resolution. I think this is by design on your end
The following browsers did not work properly:
Windows XP - Internet Explorer 7 and 8 - Failed to load custom images at top hero secion (custom CSS not contained in skeleton), alignment issues of buttons, full nav list visible (not part of skeleton issues), example grid completely broken (shows as full width divs), very broken visually but still usable
Windows XP - Internet Explorer 6 - issues above plus more visual issues. semi-usable
