Ariana has built a thing so that my friends can sort out your Xmas shopping for you. It is http://2010shopping.tumblr.com. Take a look. Someone in your life will want a poster illustrating all the ways in which the world will end, as written by a respected future strategist. A Wil Wheaton t-shirt. And I could go on, but I need caffeine, so just click through and take a look for yourself.
