picture of robert scobleNowPublic.com released Tuesday its second MostPublic index, showing the 50 most influential people in Silicon Valley/San Francisco. “The MostPublic Index is a detailed (and transparent) barometer of who’s [sic] voices are most heard in the digital landscape as new channels—Twitter, Facebook, Flickr, YouTube and the like—transform how media is created and spread.”

The Vancouver-based participatory news network rated the individuals based on four measures: online visability; presence on user-generated content and social networking sites; interactivity and accessibility; and what they call The “R” factor, presence on microblogging platforms like Flickr, Twitter, and Tumblr.

The top ten most influential are: blogger and technology evangelist Robert Scoble; TechCrunch’s Michael Arrington; Twitter’s Jack Dorsey and Biz Stone; Google’s Matt Cutts; Mashable’s Pete Cashmore; blogging pioneer Dave Winer; venture capitalist Guy Kawasaki; entrepreneur Loïc Le Meur; and Digg cofounder Kevin Rose.
