I am a big Wired fan. So I was excited to see this article covering Stanford's open course offering: The Stanford Education Experiment Could Change Higher Learning Forever. Plenty of concepts to think about - but mostly I am now even more inspired to open my own courses, starting with Chinese.
I was also really taken with the quote attributed to Mark Twain in the article. While I am not a fan of quotes in email signatures, this would make a good one: "Education is the path from cocky ignorance to miserable uncertainty."
