Have you ever seen or heard of someone using it?

Back in the days when Google didn't automatically redirected you to the results page as you typed, I think not a lot of people used the "I'm Feeling Lucky!" button. They would rather click "Search" or "Enter" and be taken to the results page and from there they'd be happy to click on the first result that Google provided (if that's the case) and repeat this over and over for as long as they needed to go back to the page.

What is so appealing about the results page? Why people like to hand-pick the results, even when the Software and the User agree on the best solution? Why would the user like to skim through inaccurate results that rank lower than the actual software's best result before they actually take action?
