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.<p>It still seems wrong to me, though;  it seems like if you&#x27;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.
