Pandora users have made over 10 billion 'thumb' ratings

"Pandora has now clocked an impressive 10 billion thumb ratings, according to details disclosed by founder Tim Westergren in Los Angeles. "We've now reached 10 billion thumbs," Westergren told an audience at Musexpo at the W Hotel in Hollywood on Monday, and the accomplishment was later blogged on pandora.com.  "Of the many milestones we've hit over the past 6 years, this is perhaps the one that makes us most proud," Westergren relayed.   "Little by little we are all collectively creating a music discovery engine that might just deliver on the grand promise of the web - a completely personalized listening experience for every user, and an effective outlet for tens of thousands of deserving artists."
