Keep exploring the possibilities, open your mind to what could be, and read through another excellent presentation on the social networking change wave we are all living and working through.
The pictures above are from this excellent slide show that follows. One of the slides in the presentation asks, "what can you do for that community." The answer: be useful. Through the radio lens I believe that to mean give your listeners things they can only get from you. Unique attributes that define your purpose--entertain, inform, interact.
As always, your feedback is welcome.
