Sonia Sotomayor's confirmation hearings last week may have topped the news cycle among the mainstream media, but the blogosophere and social media sites were far less impressed.

According to numbers compiled weekly by Pew Research Center's Project for Excellence in Journalism, the hearings didn't make it into the top seven stories among blogs and social media sites, including Twitter. The top seven includes topics that are linked in at least 5 percent of stories on social media sites.

Sotomayor "was such a main part of the dialogue in the mainstream media you would think there would be some pick-up," said Amy Mitchell, deputy director of the Project for Excellence in Journalism. "On the other hand, what folks in social media are drawn to are things that can incite change, impassion them.... Neither of those things really existed in these proceedings."

So, what were bloggers and other social media types focusing on? Sarah Palin, who grabbed a whopping one-third of all linked stories. Meanwhile, Iran dominated the Twitter platform for the fifth week in a row.
