Please expand, how would you see fit a framework that isn't like the rest? I'd love to know. Personally I don't see a lot of room for innovation in design. The early 2000s had its table-based designs, and micro designs with small bitmap fonts.. that only appealed to a niche audience. Websites then were much less accessible and had horrible UX. In today's modern design, you're either flat (Foundation, etc.) or you're Bootstrap. If Yahoo didn't mimic the aesthetics of the most popular frameworks, people would complain about it being too different, and it would not gain wide-spread adoption.
