I haven't read 100% of these posts. I feel I've read enough to comment responsibly. So here is what I have to say about this.
Beer snobs will exist. You may disagree with their attitudes, their behavior, and their general disregard for common sense. These folks are not very popular personalities with me. But yet, they exist.
Sure, extreme beer snobs make us all take a look at ourselves and don't lie and say they don't. They make us get real about what we think and feel about beer. We should be thankful for the extreme beer snobs. Those crack-head beer drinkers and self-defined critics of good beer provide us a level of balance.
If the crazy beer-snobs like a beer, it might be an interesting beer. It will be different, it will be outside of the box. It might even suck. But that typically is worked out early in the process. In the end, if beer-snobs like something, it might be worth looking at.
So with that in mind, beer-snob people might be useful to help us find interesting beers.
Now for the bad. Beer snobs often disregard a good beer simply based on who brewed it.
Seriously? Who automatically disregards a beer simply based on who the brewer is? This is where beer snobs lose. I'm amazed at how quickly beer snobs will give a well-known commercial brew a poor rating simply because it is a well-known commercial brewer that made it.
The greatest fault of beer snobs is that they believe that only craft brewers can make good beer. As popular craft brewers in the USA are growing in popularity, they are growing in production. And it seems that while these folks are growing their breweries, the beer snobs are starting to shy away from them.
The beer snobs are either part of one of two groups. Group 1 - It can't be a commonly available beer for them to respect it. Group 2 - It isn't something that is a hot topic on the internet. Or, it isn't a super rare and publicly uncommon beer.
Beer snobs are dumb. Honestly, they should all be home brewers. But if they were, I would be annoyed be them.
