I tagged all my photos back when I was still "stuck" with a PC. Switched to Mac 2 years ago, and iPhoto doesn't allow tag...it instead displays photos by "Events"...not liking this solution very much. Now that Maverick makes a big deal about tagging, I wonder if iPhoto allows tagging and displays photos by tag? That would be very useful for me. Tagging a document, however, is not as intuitive/helpful to me. As you can tell I haven't yet installed 10.9 so I need you guys to tell me. Merci beaucoup!
