To clear few things up lets discuss why Bootstrap is here. Bootstrap should be taken as a base where from we can start building our applications right away while being real agile cause it provides us with mostly used design patterns and interactions which if we require can differ from in our design iterations (!imp). So again its essentially a framework providing some conventional patterns for development which I presume is bit like convention over configuration paradigm. I would agree with the point that visual style matters as its is something which will molds into your brand identity and must be unique as all products are unique in one way or other. So yes its really a fail when most of the developers choose to maintain same Visual style in their sites which is to me is an utter disrespect of brand identity and something that must be avoided. >Consistency is good for usability. Again, Button should look like a button, but not so much like other site that user confuses your site with someone else's. As far as Usability is concerned to my understanding it is not affected in any way by fact that 2 sites have visually similar buttons but it is rather defined on the basis of content they provide and how it is presented(!imp). Difference between usability and visual appearance is quite understood I guess.
