Why have a tag feature if it's just to see the list?

I would like to be able (in my case, for instance) to email Fabricators in Los Angeles. I have a "fabricators' tag, a "New York" tag and a "LA" tag, some of my messaging only is relevant to a portion or coast.

I'm sure I;m not the first to ask, but this would really convince me to stick with Nimble.

Thanks! I know it can't be easy pleasing all of the people all of the time!
