We are now in the middle of the Social Media Challenge at DonorsChoose. Many of our generous, loyal, beautiful, intelligent, witty, and particularly well-groomed readers have risen to the challenge, and we have to date raised $3,000, reaching over 2,000 students in need across the country. Thank you to everyone that has already contributed! For those whose wallets have remained closed, please consider donating. For example, Mrs. S is teaching Kindergarten in a high-poverty area in Oklahoma, and she needs some science kits to help inspire her budding scientists. To boot, the George Kaiser Family Foundation will match your donation dollar for dollar, so you get that heart-warming “I’m making a difference!” feeling for half the price. Although I’m sure you don’t need any further incentive, in recognition that it’s a material world Sean has kindly offered up a copy of his forthcoming book as a token of thanks for those donating over $100 (of which there are at least eight thus far) .
