Here's a blurb from their About page:
The LINK-live Presidential Inaugural Event ... will connect hundreds of thousands of Americans on the eve of a new era in American politics. Over 4 million Americans will converge on Washington, D.C. to participate in the Inauguration - LINK-live will make it possible for many others in local communities and around the world to also participate in the historic celebration through online technologies.For obvious reasons, the site is targeting a mostly-left-leaning audience, but other than the focus on the Obama administration, I don't see much of an editorial slant. My deeply Republican friends may be turned off by the calls for mobilization/activism that hover around the page, but on the whole it looks like a good substitute for the long drive to the capitol.
