> It's like trying to categorize your photos in a directory tree A problem that made me think about tags instead of categories was precisely that: I have photos that I want to organize. I started by organizing them by person with a folder for each person. But how do I handle a photo where multiple people are in it? Tags don't have this problem. Unfortunately file systems don't support tags.
