This week, I spent a couple of great days at Walt Mossberg and Kara Swisher's annual D: All Things Digital conference. Among the highlights: watching Jill Sobule sing about Rupert Murdoch -- in front of Rupert Murdoch, and Facebook's Sheryl Sandberg levitate around the conference after securing a $200 million investment from the Russians. The breakout star was new Yahoo! CEO Carol Bartz -- and not just because of her perfectly timed F-bomb on the D7 stage. She was a quote machine: "Down 15 percent is the new flat" and "You can't take nine women and make a baby in one month; there is a process" were among my favorites. But the line of the week came from Martha Stewart who told me over lunch: "While Bernie Madoff was on his rampage, the SEC was busy pursuing me." For more on the conference, click here.
