It is general advice. Even if you're taking it slowly, you need to somehow let the person you are interested in know that they will enjoy hooking up with you someday, or they won't stick around to wait for you. Edit: I still need to emphasize the public element. Don’t let your co-workers and friends know you’re into them (at least don’t blame me if you do)
