Given the CLI syntax we're pushing in the search box, we were looking for a novel way to describe it. "Hashtag" caught on pretty well on twitter, so we figured with the / modifier in front of what are essentially category tags, "slash tag" would be pretty descriptive. It strikes some people as being a cheesy marketing term. Not sure what to do about that though.

You could leverage the popularity of hashtags, since people already use them and feel comfortable with them. IMO I'd rather slash than tag though.
