I've often seen questions I've asked turn in to very long threads of people chatting with one another. I'm not necessary. I get the ball rolling by asking the question and it then takes off on its own or it just lies there dormant because it didn't appeal to anyone. You enjoy driving a car. You don't need to chat with the person who designed it. You enjoy a meal at a restaurant. On rare occasion a chef will come out and chat but it's rare. You still enjoyed eating the meal didn't you? It's a serious question. I'd like to know.
