Which language is news.ycombinator.com and reddit written in?

News.yc is written in arc, which to my best knowledge is a functional lisp like language.

Reddit is written in Python using web.py as the framework. It was originally written in lisp but they changed to Python for various reasons.

Just to be a bit more technical...

Arc uses MzScheme.

Reddit was using Common Lisp but now uses Python/web.py as you said. I remember hearing that they may switch to Django.

Actually, they tried Django but it did not meet their needs so they switched to web.py.

I think it's because they like the anti-framework way of doing things (eg. calling a bunch of libraries instead of letting the framework generate code in your app directory). Both TBNL in Lisp and Web.py in Python seem to do a great job in keep your footprint small.

I thought Reddit was rewritten in Rails, but after some research I realized that I am wrong. Its Python.

If you were at startup school you might of heard Chris Anderson, editor-in-chief of Wired (so presumably their new boss), erroneously suggest that Reddit is written in rails.
