If you asked a mechanic to fix some broken pipe on your car and he used a bit of duct tape to do it.. even if it worked, would you say it was a "good answer"?
I often see the "Accepted" answer with 2 or 3 points, and then a question below that with 10+ points which has more work put into it over a longer time, so the first answer was a quick solution to fix the asker's question, but other users put work into a better answer and the answerer ends up getting points for that as well. This is great because it creates a fast answer (good thing) and a good answer that takes longer. (also good.)
As some of the comments on this thread allude to, it depends on the frame of reference. I'll assume you mean the customer is in a professional garage seeking a permanent fix and has the money to pay for it. In that case is duct tape a"good answer?" I think we both agree its not. But if the person were stuck on the side of a road and a mechanic drove by and that was all he had or if the person had no money to pay for a new hose, well, then duct tape might be a good answer (or the least of evils).
So to point out the obvious with these q/a sites, caveat emptor. One has to look at the context of the site and the question(s) asked to determine what is "right" or "wrong" and what assumptions are made, for right or wrong.
