Is it just me or would it be beneficial to the Threadless' voting and buy community to provide a tag feature?

For example, have a tag for "monsters" and all the printed and not printed designs with monsters on them come up. Then the people would have the option of selecting another tag for only showing the printed designs or not printed.

"Monsters" would easily be switched out for "Talking food" or "Obscure" or what have you. I just believe that this feature would cut down on a lot of aimless browsing through shirts you have no intention on buying.

Thank you for your responses
Oh, and before I forget... Tag, you're it.
