I saw something about political cartoons on OS home page. Maybe they weren't all political. Very few political cartoons are funny, to me. I feel if you just draw a picture and label everything in it with a topic that's "current" you have a political cartoon. Then people can use their "knowledge base" and read something into it that you hadn't thought of. That's very "sharing"  to me. It's a way to bring everybody together for a common thing and make us all "we, the people", because uh.. we are. I should have labeled that house as "the White House". Maybe next time.
