Google top 1000 sites: Interesting stats about them

Nginx with 14% of market share is indeed very interesting, very close to IIS (17%).

How can they detect the programming language in use other than by looking at .php, .aspx, .jsp, etc? You won't see this on a most professionally-authored sites that use a router and RESTful URLs.

Have a look at Wappalyzer if you're interested in usage statistics for web based applications. It also lists the most popular websites per app.<p><a href="http://wappalyzer.com" rel="nofollow">http://wappalyzer.com</a>

I'd like to see sites that use mootools, Prototype, YUI, Dojo, etc. Those are some simple statistics to compile I'd think (filename based, or just simple regex of the first 200 characters).

Where's google on that list?
