I guess there is some truth in the "emporer's new clothes" comment, I think it's just a new/Americanised term for microwbrew, which has been around for quite a while. I think it's quite distinct from the whole real ale thing though - I lost any enthusiasm for that whole scene after getting through several pints of samey, lukewarm, flat and fairly unpleasant bitter at the Earl's Court beer festival thing a few years back. Hoping in vain that I'd come across something at least semi drinkable.
