It also lets you see how pages look at that time of being edited. Each edit is recorded in the history. If you go to the Weirdmageddon Part 1 page and you look in the history, you'll see every edit that has been made to the page. It's also useful when undoing vandalism, because you can select the last good revision before the vandalism, click edit, and then revert it all.
