One of the reasons that Monsters, Inc. is doing so well at the box office right now (much better than Shrek) has to do with the demographics. Many of the people watching the film are teenagers, and they are more apt to glaze (or even laugh) than the parents taking their children.
We're much better off writing to publications, congresscritters, and other such venues than wasting time handing out fliers to people who really could give a rat's ass about free software.
