I think part of it is because it is a very process and improvement focused hobby. Cost per batch is an easy measurement of efficiency.I see it EVERYWHERE on hbt and it's driving me insane. I love craft beer and the homebrew hobby, but I can't help but notice it everywhere. I imagine some of it is just related to having a low income, but that can't account for all of it.
From complaining about the price of beer in a bar to bragging about how cheap you brew a beer per ounce. I assume if you're into beer then the priority would be to make good beer, but for many on here it seems to be how cheap you can be about it. The most annoying is when people seek to find ways around well known longtime good vendors to save $10. That kills me honestly. I'm not gonna act like I've never bought something on amazon, but I always try to support good vendors and my lhbs.
I am also into cars as a hobby and naturally see the same type of people. It's like a cancer to hobbies in general.
Am I insane?
Anybody agree?
Regarding your statement on vendors I couldn't disagree more. The only one who benefits from vedor/brand loyalty is the business who could not care less about you. I also support my brew store for grains, ingredients, co2 etc. But I would never go there for equipment because it's 15-25% more expensive than online. But I also understand your view and if you don't mind spending the extra money, good on you.
Lastly I'd just say that yeah it's a hobby. Which by it's nature usually means using up expendable income. A lot have people have that in limited quantities these days.
I guess this is a very long winded way of saying it doesn't bother me, and there's plenty of room in the hobby for all types. Relax don't worry etc etc
