I found out that kusaba x is pretty old shit. What's this whole think about generating html files? Can't it be done simply by sql queries every time and do it with some ajax? How would you write it?

But PHP isn't good enough for Facebook; that's why they developed their own PHP to C++ compiler...

Using a better language/platform would likely result in less servers, less electricity use, and less pollution.  Avoiding PHP is the green thing to do.
