Yahoo is running Apache over FreeBsd. But in terms of python use, its pretty rampant on the backend of their site. try using one of the yahoo maps and look at the script name ... .py There are quite a few high-profile sites that use python on the backend. Its very clean easily understood code from a language that can be learned quickly. I've been writing web applications in python for the last few months after switching over from perl... and i've been impressed over my increase in productivity and the readability of the code that i produce. Which is huge in terms of other people mantaining... IMO perl's great for quick and dirty stuff and get something to work but it sucks for mantainability in a complex app... which is where python begins to shine...
