It's half an hour before the CEO of Silicon Valley's hottest social network is set to take the stage, and it's already standing room only at the Startup Grind gathering in Palo Alto.
The bi-monthly gathering of tech entrepreneurs has nabbed some high-profile speakers in recent months. "The crowd was big for Kevin Rose," Dave Wamsley, a regular attendee, says of the Digg founder. "But now Elvis has entered the building."
Elvis, it turns out, is a baby-faced native of Iowa with a somewhat shy mien. Ben Silbermann is also CEO of one of the fastest-growing websites in history -- Pinterest, which lets its 12 million-and-counting users collect and share digital images and link them to websites.
