They’re back online!
After signing off Facebook and Twitter for a week as part of the so-called “Digital Death” charity campaign, celebrities including Alicia Keys, Lady Gaga and Kim Kardashian are returning to social networking – having met their fund-raising goal of $1 million for AIDS charity Keep a Child Alive.
The public and the stars involved in the campaign donated half a million dollars, while pharma billionaire and noted philanthropist Stewart Rahr on Tuesday offered to match that amount.
