This is from a Facebook App called Puzzlebee.  You can share your photos with friends as puzzles.  You can also tag puzzles, but first you have to pass a tagging test.

Bad tag!  Bad tag!  No no no!

I mean, come on.  Isn’t that the point of tagging? That I can tag something as “Fred” if I want my friend Fred to view it?  Or that I can create my own shorthand (TBR = to be read)?  I do this with tagging, and I don’t consider myself misleading other people, because those tags are created for searching purposes, not browsing purposes.

I could see librarians leaping on this idea of creating tagging tests before users could contribute tags to a catalog.  However, rather than improving the user experience, it’ll be one more hoop that we would be creating for users to jump through.  Just say NO!
