I just tweeted this today, and, frankly, it would be one of the biggest selling books of all times:

1 important dictionary was not invented yet: the FAQ one (gazillion of answerable questions gathered into 1#book)

So, actual answers to common questions, not unanswerable questions, of course, would prove to be quite a helpful dictionary, I think. Perhaps it would be hard, or time-consuming, to run through history pages, but sometimes, looking back and reading through pages of answers would be a blessing. Not even that, but what if a company would submit an FAQ as a dictionary entry, that way a potential employer would see a firm's demands, conditions and means of hiring before actually attending their respective job interview And what about those easy to harder to find questions for an online game, a program, a web site, an online safety reference, words we should be advised not to use in life or in a specific medium, people we should not meet, people we should meet or books we should read, etc.

A dictionary incorporating all those and more? If your frequently asked question has a common answer, then you would probably find it in the FAQ dictionary.
