Yahoo president and CEO Marissa Mayer was kicking herself for leaving Kickstarter CEO Perry Chen out of a speech this week. Mayer gave a toast during dinner at the Time 100 Gala at Lincoln Center, where she’d spoken about inspiring entrepreneurs, including Google’s Larry Page and Sergey Brin. But later Mayer was spotted with Foursquare founder Dennis Crowley and Instagram’s Kevin Systrom, and was overheard “lamenting how she didn’t mention Chen,” who was also standing nearby. Another who made the Time 100 list, Michael Kors told us his mom, Joan Hamburger, was “over the moon!” he’d made the cut. “Are you kidding?” the designer asked us, “As far she’s concerned, I automatically would be on the Time 100 list from birth.”
