There is a lot of reasons to choose Go over PHP for new project (static typing, better scaling because of smaller memory footprint of each request and so on). But for existing project all is not so simple. But after reading their post I understand it as they just got tired because of code mess, so rewrite was only way to clean things up. Only thing I don't understand is why they didn't remove PHP at all.
