I /feel/ like this gist is largely on the money, and also uninteresting at the same time. All languages suck, and often suck in different ways for different users. We just have to pick the one that is working best at the time, and that we're best at working with.

I will say that I do like the act of writing a pro and con list for a language or tool though(which is why I read the linked doc), and I often push co-workers to do so when they're suggesting things. Sometimes it shakes a bad choice out just with the simple act of jotting down a 5-point list.

Unless, of course, there actually is an ideal language out there. In which case I retract my point ;)
