“Netroots” is grassroots political activism organized through blogs and other online social media.
The term was coined by Jerome Armstrong and is used in his 2006 book co-authored with Markos Moulitsas, Crashing the Gate: Netroots, Grassroots, and the Rise of People-Powered Politics, in which they note “the netroots activist, much like the new generation of grassroots activist, is fiercely partisan, fiercely multi-issue, and focused on building a broader movement. It’s not an ideological movement — there is actually very little, issue-wise, that unites most modern party activists except, perhaps opposition to the Iraq war.”
