I think we need more frameworks like Bootstrap. If people are wanting to simplify design by conforming to a framework, why not give them more choice so we don't end up with a hundred websites which all look like Twitter?
I'm making one right now. But it's not a standard framework, it's a sass framework, so the 'utility classes' are pushed back to css mixins and they take parameters so they are all super flexible. I'm really excited to put it out and it's getting there, but there's a lot of polish left to go.
If anyone is interested in helping out or testing, look me up (my name is jeff escalante) and send me an email.
More frameworks like Bootstrap is not a bad idea. But, if you don't want a hundred websites that look like Twitter, then perhaps the right answer is having a themes that are based on Bootstrap - like what http://wrapbootstrap.com/ and http://bootswatch.com/ are doing.
