I often use the feature the same way. It's only "up for everyone in the world to see" if everyone has the URL, and nothing I ever share is so sensitive that the risk of someone bruteforcing all of the possible file/folder names in my Public folder poses a threat. (I imagine Dropbox would catch on to such attempts at the network level, anyway.)
