Every time I start a new web project I always know in the back of my head that someone, somewhere has already probably done this (possible better). I've always been fascinated with the architecture of some of the big name websites like Google, Facebook, MySpace, Yahoo, Slashdot, Digg, etc. and what their application architecture looks like. For example, are they LAMP/WAMP, J2EE,.Net, Perl/Python, etc.. I've seen tons of material written on Google and their architecture but is there a website that lists the application stack for these sites? Possibly other sites or is that information far to proprietary?
