Notice that the two examples you gave belong to a fairly narrow field - statistics, something that seems to be the trickiest to collect in more or less structured form. But try it yourself, you'll see how easy it is to find virtually anything nowadays. In most cases there's a good chance someone in the world thought about something you are interested in and has put it out on the Net already. If you are the first to ask a question, then I doubt WA will give you useful results either.
