We might have debated who invented the Internet, but there’s no debate over which candidate brought the Internet into political campaigns. In 2003 and -4, Democrat Presidential candidate Howard Dean made fundraising go digital.The brains – if not the functionality, design, and execution – behind that operation belonged to Nicco Mele, a 20-something year old webmaster who had worked for various advocacy groups.Since that online revolution, Mele has launched his own firm – EchoDitto – which helps organizations gain greater impact through technology. He also is a lecturer at Harvard’s Kennedy School of Government and author of “The End of Big: How The Internet Makes David The New Goliath,” where he warns against – of all things – the disruptive and perhaps dangerous power of the Internet. Among the areas he worries about: Digital’s potential destruction through polarization of politics and government.
