Prez Art Gorski read what John said about tagging photos and files in his email just now. Here's Art's comment, "This reminded me of Gmail, where, unlike normal IMAP email, you use tags instead of folders. Methinks this, like documents in iCloud, is another nail in the coffin of a file system with folders. Apple has apparently decided that most folks can't deal with a directory structure. Want more proof? Spotlight searching for documents and All My Files in the Finder."
