Thanks for the color. I'll add one more thing against my argument:

- Discoverability: How many times have you opened glossary of a book just to explore and discover what else is in this book? Or open up a telephone directory with no specific person or business in mind, but a general category - "Shoe repair"? I think when things are organized by category, it allows for discoverability which would be difficult in a flat-searchable structure. Search works great when you know what you're looking for.

This can be half-solved by listing all items in a tag. Just that they'd appear in multiple tag archives as duplicates.
