Yeah, I've noticed this too. Tho here in GF-W, Newfoundland, the 'beer' of choice is usually Coors Light or Bud Light. Why, I really don't know, but my hypothesis is that there are truly very few BEER drinkers out there anymore. What most people have become are 'soft, fizzy, alcoholic beverage' drinkers; kinda like how many girlies claim to be 'on the wine' when, in reality, they are drinking an overly sweet, fizzy, fruit flavoured spritzer by the name of "Boone's". That shit ain't wine -- it's not bad per se, and I've been know to have a bottle or two over the years, but it's NOT WINE.
In line with this theory, those who moderate (well, usually :) their consumption tend to enjoy more full bodied beers. Anything with higher malt, hop, etc. content will start to turn on you if you over-indulge (higher calorie content, worse hangovers, dry towel-tongue). Coors can be drank to excess without any of that (hell, I once couldn't even get a buzz on with that shit no matter how I tried.)
