How Popular is Twitter Bootstrap right now?

I have been using a themeforest theme for the first version of http://www.kodesk.com and it gets very cumbersome to update very quickly. Too many jQuery plugins I don't know about, to many dependencies and you end up not really understanding how some CSS classes work too. And support is clearly lacking.

Now I'm completely rewriting the site using Bootstrap because 1) its documentation is simply awesome and 2) being an open source project, the support is likely to be much better.
