Society has certainly changed. What was thought of as indecent or out of bounds now seems no big deal, and reality TV producers are following that radical lead. They're stripping plots to the bare bones, so whether it involves wilderness survival, buying a home or -- in this VH1 entry -- meeting the opposite sex, clothing is no longer required. Filmed in an exotic location, "Dating Naked" follows men and women in the buff on dates free of preconceived notions. At the end of each episode, the romance seekers analyze what they've learned before deciding whether or not to pursue prospective matches.
