Can someone tl;dr me the benefits of this new language? I am not a big fan of Facebook or php.

I would say that the fact it "interoperates seamlessly with PHP" is the main benefit, due to the new features as listed in the front page. And it is directed to people already using PHP.

As an aside, we could say that Scala : Java :: Hack : PHP?

Closer integration with HHVM than plain PHP
