What do you think of FAQs -- do you look at them? do they answer your questions?
On websites I work on, I encourage people to avoid them at all costs. Instead, it makes sense to take people’s questions and make sure those questions are answered within the text, in the place where it makes the most sense.
In my view, FAQs are a convenient vehicle for the creator, but not necessarily the best delivery method for the visitor to the page. Jacob's guide is a thorough how-to, if you do decide to use them.
