The "diff" links in the page history will show you the changes between revisions (diff = "difference [between this revision and the previous one]"). You can also check the latest changes made to a page by putting ?diff=cur at the end of the URL. (ex: http://creepypasta.wikia.com/wiki/Creepypasta_Wiki?diff=cur)

Edit summaries can definitely be helpful, but actually checking the changes made is also a good habit to get into. I've caught a LOT of users accidentally screwing up the page formatting via visual mode errors (which of course they didn't include in the edit summary), and even a few not-so-innocent users (read: vandals) putting things like "Fixing spelling errors" in the edit summary to evade detection.
