I've been part of the conference 'industry' for about three years. I generally attend about 20-25 conferences per year covering a variety of disciplines from software, to medical, to business. It is from this experience that I must unfortunately disagree with your view point :)
Regardless of the quality of talk, you can't escape a couple of people with "that guy" syndrome. Some people just can't sit still without making their opinions heard. Buzzword bingo from the article is a good example. There's often a king-nerd who need everyone in the room to know that he too is also smart, so he starts dropping stupid buzz words only marginally related to the topic.
I've seen people go up to the microphone just to give book suggestions to the speakers. "Oh, you like the subject that you presented about? I too know about this subject. I read books."
It's all veeeeeery painful to endure. So, in short, I wouldn't judge your talks by whether or not you get a couple of dumb questions.
These people exist, but they are outliers, and you can detect and discount them. If you're getting good questions, yes, you'll get a couple of these guys no matter what, but the rest of the audience will react to them for you.
