In this new post to CiteWorld.com, they're making the claim that the Hack language from the developers at Facebook is the "silver bullet for user-developers".

How do you modernize the way we build the web? That's the question at the heart of the release of a flurry of new languages and development platforms -- all from companies that run and build large scale web services. [...] While getting more out of CSS is good, as is replacing JavaScript; Facebook's HHVM and Hack combo is targeting one of the foundations of the modern web: rapid application development.

They talk some about the overall goals of Hack (improved performance, a stricter typing system) and include a brief example of some Hack code. They consider it to be a "more modern language" that brings PHP-based development up into a different level of languages. He also talks about HHVM a bit, migration from PHP to Hack and the potential for Hack to be adopted on other platforms outside of the current HHVM runtimes.
