Frankly, that’s splitting hairs. The notion of ‘tags’ has done 3 things:
- Given us an excuse to lauch websites without a pre-defined categorization schema, and allow that schema to grow and change over time.
- Made it acceptable for things to live in multiple categories.
- Gotten completely out of hand.
For me, there’s not difference between categorization and tagging – especially if something can belong to multiple categories.
“Tags” are good for 2 things:
- Making it easy to describe things that computers have a hard time parsing from audio, video, or images; i.e. “my dog”, “yummy cake”, “blue shirt”.
- For text – including things that shouldn’t, couldn’t, or weren’t included in the text – i.e. resturants with bad services. Tagging with the same words that are included in the copy is a complete bonehead move.
