I subscribe to a publicity e-mail list that provides a daily listing of media outlets that are looking for specific experts or willing interviewees.  I scan these lists for possible author pitches.  Here are examples of what media outlets are seeking:

-Heinous Work Uniforms From Your Past
–Commute by Scooter in Hampton Roads, Va.
–Trends in Auto Body Paint
-Motivational songs for companies
-Expert on cornstarch needed
-10 products for the perfect man cave
–Seeking a republican voter in DC
–Bedbugs in Providence area

Any takers?
