Today’s package is whimsical, mostly because I am in that kind of mood.

• One Mad Men episode worth watching from each season that is worth rewatching. Thanks New York magazine for basically making sure I don’t do anything before Mad Men mania sweeps over me & Twitter.
• Why we are in a new gilded age. Paul Krugman reviews Capital in the Twenty-First Century by Thomas Piketty.
• Letterman’s last great moment: Outside of John Gruber’s Mac-related stuff,  Bill Simmons’ pop culture commentary is must read for me, and this piece about David Letterman doesn’t disappoint.
• Just cheer, baby: The life of a cheerleader isn’t fun and games. The hard life leads to a Raiderette suing the football team.
• Is there anything beyond quantum computing? Scott Aaronson tries to answer the question.
• More time is better than more money, says Kevin Kelly. I agree with him, but only when I have enough money in my bank.
• Pimco’s Bill Gross picks up the pieces. Sheelah Kolhatkar tells the story of the investing legend who has been dealing with negative press following the exit of his CEO Mohamed El-Erian.
