Newsweek thinks Sarah Palin might be over:

Between February and April, according to an analysis for NEWSWEEK by General Sentiment, a company that tracks and measures online content, posts involving Palin fell 38.3 percent, to 235,032, over the past 30 days. Social-media mentions dropped in lockstep, down 32 percent over the same period, to 135,421. And the value of all that “free” media dropped roughly by half during this period, from $63 million to $33 million. While it would be foolish to count her out, it is hard to escape the conclusion that her influence has peaked. People close to Palin acknowledge that she has done virtually nothing to lay the groundwork for a campaign. But they don’t see her as toning things down, saying she is busy giving speeches (for as much as $100,000 a pop) and tending to her five kids and her grandchild.

It's good to have some statistics that confirm everyone's suspicions: Sarah Palin's influence is collapsing and soon she'll be a frigid white dwarf of conservatism in some far-off galaxy, far away from the general public's consciousness.
