Right now our approach is to interoperate with other libraries. Bootstrap works pretty well with React (see https://github.com/facebook/react/tree/master/examples/jquery-bootstrap https://github.com/facebook/react/tree/master/examples/jquer... for a small example). However it's definitely possible to build a component library with React, we just haven't done it yet. If anyone wants to build bootstrap or jQueryUI bindings, we're taking pull requests :)
