In doing a new website, our client provided us with a quite long list of FAQ (Frequently Asked Questions). As usual in these cases, questions are made up (a totally different question, but a whole important matter by itself).
We told the client to shorten the list because we discussed it and we thought it gave the impression of a very hard to use site (which it isn't). While hesistant, the client accepted our point of view.
However, this subject kept me thinking for the last few days, so my question is: is there any study or research proving any kind of effect of large amounts of questions in FAQ? And if so, is there somekind of rule or magic formula to get the perfect amount of questions?
