To be fair, I don't think you can reasonably consider Facebook's mega-crazy (mega-crazy being applied without value judgement) PHP-to-C++ scaling method to be the same as surviving using a scripting language. You can also argue that (most) of the heavy lifting Github does is in git itself, which is an amalgamation of C, Bash and Perl.. and the "good" stuff is all in C. Bash is mostly interfaces and perl is for random stuff like sendmail, cvs import, etc.) Just because your Java team was slow doesn't mean all of ours are ;)
