Tweeting on behalf of brands is a lucrative business for some celebrities

How’s this for a day’s work? “Rappers 50 Cent and Snoop Dogg have earned more than £3,000 each for a single message on [Twitter],” reports The Sun . Arnie Gollov-Sing, a 38-year-old Briton, has signed 5,000 names to promote products such as Coke and Microsoft in America, according to The Sun . He plans to launch the service in Great Britain, where — unlike in the U.S. — paid tweeters don’t have to identify a tweet as sponsored.
