Celebrities on Google+ in Week One

It took nearly three years from Twitter’s 2006 launch before celebrities started flocking to the service en masse (although MC Hammer was an early adopter -- see timeline below).

But Google+ has attracted a number of big names in its first week beyond tech-savvy actor Ashton Kutcher. These celebs include singer Taylor Swift, 2012 Republican presidential candidate Newt Gingrich, and yes, Facebook CEO Mark Zuckerberg, currently the most popular person on Google+.
