Coca-Cola has launched a social media campaign that will send three bloggers to more than 200 countries over the period of a year.

The campaign called "Expedition 206" is part of the beverage makers Open Happiness marketing effort launched at the beginning of the year.

Coca-Cola has selected nine finalists and is allowing fans to make the final decision by voting for their favorite candidates on the Expedition 206 website through November 6. Fans can vote once each day during the three-week voting period.

Things just keep looking worse for Facebook’s Beacon: Coca-Cola and other advertisers are opting out of the program; there may be legal troubles ahead; and some investigative security work shows that Beacon sends information about user activity even when logged out of Facebook.
