Kevin Rose, the dude who started Digg, got the Twitterverse all aflutter yesterday by suggesting that Google is working on a bona fide Facebook competitor -- to be called Google Me, according to his "very credible source." All such rumors ought to be treated with a healthy dose of skepticism, but today there's been some corroboration from one Adam D'Angelo, Facebook's former CTO. Adam, again citing reliable sources, tells us Google Me is a real project, with significant resources invested in it, and an indication that "Buzz wasn't enough" to counter the social site's growing presence. Another former Facebook exec, Richard Cooperstein, makes the astute observation that what Google's really trying to do is reclaim time that the ''book has stolen away; he notes that time spent on Facebook relative to Google search and YouTube continues to grow, and the Mountain View outfit has to retaliate to keep itself ahead. You'll find the K-Rose tweet after the break -- he deleted the original, but Google Cache can be a cruel mistress.
