Since day one I've stored an arsenal of Truecrypt archives in my Dropbox folder for anything that I really don't want anyone else to find out about. (Not that there is much of that.) Most of the rest of what I store there is ebooks, university lecture notes, my portfolio, and other stuff that I wouldn't worry about if Dropbox really dropped the ball. Seems reasonable to me to be a little more in charge of your own security instead of handing off responsibility to people you don't even know. Still, I agree that we should be holding Dropbox (and similar services) to a high standard, and they have indeed stumbled on this issue.
