Yeah, I had the same question. The PHP syntax definitely puts me off. That said, it's just the front-end. Might as well keep on keepin' on with what you're using, and since it's open source, just rewrite the thing.

Deep down inside I wish they were using ERB (or HAML) however, and he was writing HERB (or HHAML). I'm still enamored with Ruby syntax, and wish it would get some more big business love.
