Mood lighting? Really? Is this 1978? The height, openness, and color of a space are what get people to like or dislike their environment, and its very easy to control.
Boards.ie is basically a moan-tank. I wouldn't use that for much of a pulse. I have been envangelizing about appreciating beer since I moved to Ireland about 2 years ago. I have converted almost everyone that I see regularly into a beer appreciator. I do it by not judging their tastes, but just buying something interesting when its my round. They all are out trying new beers now once in a while, and its as many women as men.
This is the first time I've honestly even had the conversation about how to do it on a larger than social scale... and if I hadn't started brewing about 4 months ago I wouldn't have known about ICB. But to be honest you won't reach too many people by railing against the Macrocrap, or even trying to educate the drinking public with charts. I drink Heineken once in a while, and I often go to my local where I only drink Guiness because I like the barman. If you try to include people, to give them the thrill of discovery, then you'll reach them. And it happens on a very low level.
You have to make things cool... when something comes into style people will throw away their preconceptions pretty quickly. Happened to almost everyone I knew in college at about age 20, they discovered some interesting beers and suddenly they realized its not a scary world out there. Some of them still prefer lager, but honestly being a lager doesn't not automatically make a beer inferior. People there would often switch between expensive micros when they just have a couple, and cheap swill when having 10 of them. Being militantly Anti-Macro-Man will turn all of those people off to the cause.
