Sharing with people and having them ask if you distribute.
I like all the replies!
In addition having people skeptical at first (as they are BMC drinkers) have my homebrew. Then remark, "Damn, this is good!. Have you thought about selling it?".
knowing that there are people that would sell their soul, for something you make for yourself...and do, to corporate megabrew..and you sit in a homebrew forum talking trash about their master, and get away with it!
and better yet, we haven't had to start doing drive by's on each other yet!
