I know people who are compulsive about having a clean Gmail inbox, and who derive lots of value from tags. I also know people (like me) who are perfectly ok having 10k messages in their inbox, and searching for stuff as required.

The nice thing is, Gmail supports both of these use patterns equally well.

Ideally, that's how every product should treat it's more advanced features. If a user spends the time creating taxonomies they'll never use, well, that's more the user's fault than the software's...
