Even though I've moved on to Python, I will always soft spot in my heart for PHP. The one thing that PHP still has going for it is it's ease of deployment. Everyone supports it, and launching it doesn't require any configuration whatsoever. That being said, there are certain instances where using PHP is actually refreshing, so seeing new stuff like this gets me stoked. I like the fact that they don't tout themselves as an MVC framework, but rather a collection of independent modules that end up being an HTTP request/response framework. Cool stuff for real.
