Take a peek under the hood with Builtwith.com

Ever wonder what technology was used to create and deliver the content on your favorite site?  Builtwith.com allows users to peek under the hood and learn about the technology used in any site. Gary Brewer, Builtwith's founder, says that the goal of the site is to "...help developers, researchers and designers find out what technologies pages are using which may help them to decide what technologies to implement themselves."  Find out more by reading the FAQ page or the blog post on Read/WriteWeb.

I think that this would be a great tool for those librarians that are responsible for their organization's website.  If you're thinking about implementing technology changes for your site, use BuiltWith to find an example that can help your decision makers better understand the changes you are proposing.
