Instead of asking for others to share the knowlodge they've already earned, try playing and then critique your own play. Part of the fun of gaming (and life) is learning and achieving not vicariously but by experiencing.
I generally agree that this is the best way to approach gaming. OTOH, there are certainly lots of people who scour the Web for strategy tips. I don't imagine the gentleman's wife is one of them, but I have to admit there are times when after several plays, I still don't **get** a game, and I'm appreciative of those who don't mind sharing their perspective on the game. I don't see how sharing expertise is a bad thing, generally. Perhaps it might be preferable if it was done in a private message?
