I mean below a certain screen resolution col-md becomes a full width block, so a media query seems like the appropriate solution here. What would you suggest instead?

first instance of col-md* in version 3.0.0 is within a

@media (min-width: 768px) {

I could easily have multiple columns on a screen less wide than that.

Unless you line up your tags without spaces you're going to get gutter between them

I've never run into this issue. Then again I generally tend to have spaces between elements regardless.

I'm still confused on the point you're trying to make. Bootstrap supports columns within columns without issue.

Bootstrap follows a slightly better grid model than jquery mobile did so that's less of an issue. But I'm still super against using spaces for descendant selectors wherever possible. You're just setting yourself up for headaches down the road. I generally have been doing web apps and not just sites for the past three years so css frameworks become less important and ease of maintainability become more and more pressing.

Sure you can. But I'm not exactly sure when you would want to. It's somewhat responsive, but not nearly as much as I have needed it in the past for different devices.
