So coincidentally I work at Facebook and know a bunch of these guys pretty well, but I don't actually interact with the Hack stuff at all (as I work in infrastructure doing flash and network stuff, primarily). I recently played around with the Open Source hack stuff and I installed it on my VPS.

Has anyone else played with Hack in a productionish environment? I'm just wondering what deployments and stuff are actually looking like in the world outside of Facebook.

p.s. tutorial that really exposed me to hack is here: http://hacklang.org/tutorial
