Hacker News is written in Arc, a dialect of Lisp: http://en.wikipedia.org/wiki/Arc_(programming_language) http://en.wikipedia.org/wiki/Arc_(programming_language) Reddit used be written in Lisp, but they switched to Python early on: http://blog.reddit.com/2005/12/on-lisp.html http://blog.reddit.com/2005/12/on-lisp.html I do agree that they look alike, Hacker News was inspired by Reddit.
