Home to more than 3,000 charities and nonprofits, 270 neighborhood associations, and dozens of coalitions and community groups, New Orleans is in the midst of a civic renaissance.  Frustrated with inept and inefficient local and federal governments, the people of New Orleans have harnessed the vast power of the Internet to network, fill their needs, and reach out to the traditional media.  Armed with blogs, Twitter, Yahoo groups, and wikis, nonprofits and citizen groups are transforming grassroots community, organizing into a potent force that is helping to determine how New Orleans will be rebuilt.

Yet what makes post-Katrina New Orleans unique is the degree to which digital networks have become ensconced in physical communities, even four years later. This digital revolution is not limited to bloggers and tech geeks—many people who had barely used the Internet before Katrina for more than sending e-mails are some of the leaders of the grassroots digital activism movement.

So I Twitter, and then everybody knows my deets.”
