What is the tagline supposed to be used for?

Hi I'm new to Zen Cart, and I'm just wondering if anyone would kindly tell me what the tagline is meant to be used for.

I notice it appears in the browser title, which seems to duplicate the function of page title. It also appears in the header area, which may be of some use, although I can't think of anything specific right now.

I know it can be removed, but as I'm new to Zen Cart, I'd like to know what its intended purpose is before I decide what to do with it. Thanks!

You would use it for displaying a short, pithy explanation of what you shop is, or why people should buy from you.

A few examples:
"the biggest and best source of catnip online "
"America's leading supplier of chastity belts"
"free deliver on all products over $1m"
"no-fuss delivery and returns policy"

It can be the same as the page title, but is more prominent.

That makes sense, I think I can use it.

Thanks kuroi! :D
