Similar Question:
Hosted version of Twitter Bootstrap (maybe Google?)
Currently, I am including my jquery script from google's servers in this manner.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
Twitter Bootstrap is one of the most widely used projects on github. It continues to gain popularity daily and is utilized by numerous websites.
If there was a centralized API for loading bootstrap, it would significantly improve page load times as it could already be cached in the client's browser, similar to jQuery.
Something along these lines
<link rel="stylesheet" type="text/css" href="http://bootstrap.twitter.com/2.2.2/bootstrap.min.css" />
<script src="//bootstrap.twitter.com/2.2.2/bootstrap.min.js"></script>
Is this concept feasible?
