Great, Another Bootstrap Site
Bootstrap gives us a sane, standard look and feel for the web, which is a good thing.  The design community generally doesn't like the idea of standards because they are a creative community, and there is no more damning phrase in the creative communities of the modern era than "unoriginal".  But unoriginal is exactly what most people want with most of their web applications: they want to know how to work the things instinctively and not learn another UI for this or that task.As a small example: with bootstrap, buttons look the same, so users instinctively recognize them without additional mental effort.  Developers can focus on developing applications that are functional and usable, rather than tweaking CSS to make things "look right".I think bootstrap, and the non-coercive standardization of web applications it is fostering, is one of the most important developments of 2011-2012.I do think means there will be less need for straight-up aesthetic designers, with UX and information architecture becoming more important.
