Obama finds that the Internet bites back

[commentary] For a man who came to power by harnessing the potential of the Internet, President Obama has been oddly out of sorts in recent days as the medium turned against him. During and after Obama's 2008 campaign, his advisers crowed about how they had found their way around what campaign manager David Plouffe called "the snarky media filter." In a typical iteration, Plouffe bragged, "We reach more people when we send an e-mail than on most nights watch 'NBC Nightly News' and all the cable news channels combined, including Fox." After helping to undermine the position of the media, Obama and his aides are now feeling the consequences of the decline.
