Many answers are long, maybe including some cut and paste of some online dictionaries. I find this annoying, and usually I don't bother reading answers that do not go straight to the point. Should answers be more concise? Should users encourage a bit shortness of answers?
I see my vision is not shared by many and I respect that. On the other hand many other SE sites have usually shorter answers. Long answers are good for native French speakers, but not for learners that really don't need a lecture on the nuances of the French (which is still interesting but not always useful). It would be interesting to have some statistics on the length of accepted answers compared to that of all the answers on FL&U.
