Anyone remember a few years back when George Clooney railed against Gawker's Gawker Stalker columnof celebrity sightings? Well, he and thousands more celebrities might not be happy with the launch of JustSpotted.com. The site, which launches Tuesday, will inform users of where each of the 7,000 celebrities that make up its database have been seen last, anywhere in the world. The site is different from the Gawker Stalkers of yesteryear because it gets the whereabouts of celebs via a relationship with Twitter that gives it access to public tweets, which usually number 50 million a day. The Hollywood Reporter, which broke the news, explains that "proprietary technology uses 'natural-language' filters to figure out which tweets pertain to celebrity sightings. "We've been working very closely with Twitter for two years," JustSpotted founder and CEO AJ Asver told THR. "We're one of a handful of companies that has that sort of relationship with them." Asver said that JustSpotted.com is not meant to encourage stalking. "We're not asking people to change their behavior," Asver said. "The information isn't real-time enough for you to run over there and see them." JustSpotted won't give exact addresses of a celeb's location -- it will list just a restaurants name, and city, and virtual pinpoint on a map. And the site doesn't limit celeb sightings to the United States; JustSpotted will track celebs worldwide.
