That now-famous catchphrase is widely credited with giving the Clinton campaign its win. Although we don't know if it was ever taped up on any doors, I think the winning strategy for the Obama campaign was "Transparency, stupid!"

In this election, Obama rode a tidal wave of youth vote to the presidency, with 66% of voters under 30 casting their ballot for the Democrat. What the campaign realized, early and often, is that the under-thirty crowd communicates differently from the rest of us. As Allison Fine writes in Momentum, this group is "... likely to engage in two-way conversation with staff, volunteers, and clients, rather than in one-way broadcasts, the style of communication most often used by organizations now."

This meant two things for the campaign.
