They were easy enough to do, why not do more?

Tags vs. Hierarchy

Tagging Advantages:

• Results are much more contextual*
• Community tags
• Fits into many ‘categories’
• Tags are user generated
• Not lost in a sub-sub-sub folder
• Findability increases
• Learning increases

*With hierarchies you are limited to one category in which to place information.  In reality, one piece of information may fit MANY different categories (sub-sub folders for example) and may fit in one for a particular context and not in the same for a different context.  Tags allow for more than one ‘category’ and this information is not pigeonholed into one.
