I use Wikipedia almost every day. When we left a trivia night early, I looked up Lou Diamond Phillips the next day to learn that his first wife left him for…Melissa Etheridge. Dean and I have roadtripped down to SoCal, alternating reading Wikipedia on our Blackberries: the Kennedys, the Chappaquiddick incident, P.T. Barnum. If you go to the site now, there’s an urgent appeal from the founder to donate. Make this your one last good deed of 2009. It’s so important to give to this free service.
