Hm, I'll be the asshole and point out something that to me is kind of obvious: Bootstrap isn't mainstream enough to warrant it's own foundation/organization.
Just looking at the caliber of other projects that have gone this way (at the top of my head: Apache, Drupal, Django, Zope...) and looking at Boostrap I don't think it's even close to the userbase/clout needed to pull this off. Even the maintainers of those other projects, successful as they are, tend to have a day job.
I don't know, maybe I'm reading too much into this, but I think it might be a little to early to make this move. Just my 2c.

What do you mean by "not mainstream enough?" Organizations on Github are simply a convenient place to put one or more projects that are collectively worked on by a group of individuals and do not necessarily have a single core maintainer.
Yeah, that's what a lot of people seem to be missing here: there's mention of an open-source organization on GitHub but no mention that fat and mdo want to start working on Bootstrap full-time and make money off of it.
Sorry, what I meant by "mainstream" is "have enough of a following". You can say a lot of good things about Bootstrap, and to be fair most of them are probably right, but even when you compare to other jQuery libraries/framework it must have... what, maybe 5% of the users? Also, it's a very young project, it's not an established de facto piece of technology like Django is when it comes to Python web frameworks, Rails to Ruby web frameworks, or Apache is to HTTP servers.
