CoffeeScript is much much more than just avoiding extra brackets. Anyone avoiding it because of the hype should do themselves a favour and check it out before dismissing it. I can't quantify the amount of time I've saved both reading and writing CS instead of JS, but it's gotta be in the 10-20% range.

And please, can we drop the "hipster" meme around new languages/tools? People experiment and adopt promising new technologies because they see a benefit to using them.
