Will this fill the void of CSS frameworks for rapid WebApp development? Bootstrap is fine, but even in Responsive mode it is not made for developing sound application interfaces on the mobile form factors. The grid adjusts, but the elements do not do a good job of resizing for touch over mouse use. RatchetUI (http://maker.github.io/ratchet/ http://maker.github.io/ratchet/) seems to be the best hat in the ring currently (one of the lead devs is one of the guys from Bootstrap and another is from Zurb); but the commitment to project leads me to believe even the founders aren't sure what they want out of it.
