The web offers tons of tools to become more of an individual - or to at least make you feel that you are a special individual - even on a planet of 7,000,000,000 people. It's easy to make lots of stuff in your world unique to you. We can all think of examples from your music collection to the color of your screen saver. Every product works to make it as 'personal and individual' of an experience as possible.
No one wants wants to be 'wearing the same outfit' in today's world and overall it's pretty easy to become so individualistic in your virtual/web world that even with 7 Billion you are an individual.
As we go beyond 7 billion next year remember that the audience will be looking for more and more ways to preserve their individuality -- even in the face of the 1 in 7 billion odds. Something to keep in mind as you program your station and hang with the local audience in your market.
