Well, a marketing expert is a guy who watches TV (or listens to the radio, or surfs the Internet) for the commercials. I'm not sure that I've reached that state yet, but I have to admit to paying lots more attention to commercials than most of my friends.
This morning as I drove to work, I was cracked up by a radio commercial for something called GetLoaded.com, promising to match truckers and shippers "on 11 different levels of compatibility" — a fun parody of eharmony. com (although not the only one!).
And, as Andrew Newman recently noted in an article in The New York Times, humor has its place in advertising for attorneys as well. I guess I'll just keep watching the commercials.
