great idea, and excellent timing as well tbh. The TW Bootstrap look is getting very common out there. My site is built on it and I can see the vanilla TW Bootstrap look ageing very fast.
Seeing Bootstrap everywhere is actually a good thing. It makes me hope that the Web is finally maturing to the point of having a common, uniform UI patterns for its applications.
If Bootstrap helps to alleviate the design & UX bonanza that many of the present day web apps still is, it will be just another stone in its awesomeness bucket.
