Google code analysis and another nifty Firefox extension

Google have released some statistics on web pages they have analysed:

In December 2005 we did an analysis of a sample of slightly over a billion documents, extracting information about popular class names, elements, attributes, and related metadata. The results we found are available below. We hope this is of use!

I would very much say so, so have a read about Google code webstats

Another Firefox extension I hadn’t known of earlier is Firebug which put together the best of JS console and the DOM inspector and even shows you your XMLhttpRequest data!
