Nick Rubin is a high school student. His father, a longtime friend and senior lawyer at Microsoft, pointed me to a plugin Nick was building to scan the page you’re reading in a browser, and highlight the names of Members of Congress. When you hover over the name, you see from whom the Member gets his or her money, what percentage of the Member’s money comes from small dollar contributions, and whether he or she has committed to fundamental reform (drawn from the site reform.to).
Easily the coolest plugin that I use, now available for free. You can get it at AllAreGreen.US. (The website concatenates the site’s great slogan: “Some are red. Some are blue. All are green.”)
