I agree that there's a big difference between "it's not as good as that one" and "I like that one better".
@squeegeethree while I also agree with you regarding innovation, I believe if you're brewing an ESB, for example, brew it to style. Otherwise don't call it an ESB. Call it dannyboy's bitter mashup or something unique. That way when less informed friends taste it they won't judge the category by your unique out of style beer.
Likewise, I don't believe the style guidelines should be expanded so quickly to include beers that may just be a passing fad of the current craft beer consumer. How long do you really think the milkshake beers are going to be around? Classic styles are classics because they've stood the test of time...OK my rant is over too.
