Many thanks, first of all, to Chris, Roderick, Aeon, and Stephen for their contributions on Ayn Rand's centennial.
To give a somewhat different take, a long piece at Positive Liberty discusses Ayn Rand's influence in my own life. It's aimed mostly at people unfamiliar with her work, but L&P readers might find it interesting too.
I've even done my best to give it a provocative, Rand-esque title:
"Is She Good? Is She Evil? Ayn Rand at 100"
