Mark Perry runs a great blog called Carpe Diem and I encourage you to check out some of the things he posts. This particular link will show you the Google hits and Amazon books sales graphs for the book Atlas Shrugged by Ayn Rand.
If you haven’t read the book (and as of this post I haven’t, but it’s sitting next to my bedside waiting for me to finish up the book “Blink”), it is a novel published in 1957 that was an expose on socialism and the loss of individual rights. It begins with a simple question, “Who is John Galt?” If you’ve seen that on a tax party day sign, this is the source.
Here is a video with pictures of Ayn and quotes from the book. The quotes go too fast to read them completely so you’ll have to pause the video periodically.
