Wow. I guess things have really changed since I was in college. Waaaaaaay back then - late 1990s - we didn't ask about the source or quality of the alcoholic bevvies at parties we attended. We only cared about 1. Is it cheap? and 2. How schnockered can we get?
Let me respond to your points in order. 1. Who cares? Ooo, big bad wolf. 2. and 3. I really think laughable. In all my college days, I can't remember a single kegger where we stood around and discussed anything other than "Dude, dig that hottie over there" and "Gimme another beer". In non-party conditions, yeah, I'd share a bottle of something interesting with someone I knew would appreciate it. But not standing over a keg in someone's basement or backyard. And hell, if you do manage to recruit a new brewer in that environment, it'll be someone who wants to make booze cheaply, who'll get bored and frustrated with it, and fall away from the hobby just as quickly as he was attracted. I've seen it happen. 4. I got no problems with, other than I'd rather share my libations with people whose primary motivation is appreciation, not inebriation.
That's not pompous. That's a statement of what I believe to be fact: In the first place I'd like the OP to not waste his time, and in the second you're missing the point. Yes, this hobby is for everyone, including those who want to brew cheap, tasteless swill. This board, however, is not; this board is for people who want to lovingly hand-craft flavorful, exciting brews.
Cheers,
Bob
