I was going to argue with you; but look at facebook. They started with PHP... instead of re-writing it in something sane, they wrote a better php runtime.

I was going to argue with you; but look at facebook. They started with PHP... instead of re-writing it in something sane, they wrote a better php runtime. So perhaps you are right. It still seems wrong to me, though; it seems like if you've got several orders of magnitude more resources to build version 2 than you had to build version 1, you could re-do it from the ground up in something... better.
