What do you think the most useful projects would be to humanity which could be helped or solved using a website? Can you name any that are running strong now?
(Representative) Republics use hierarchical voting: citizens elect representatives, representatives vote on issues and elect representatives from their own pool for higher bodies. Democracies give one vote to every citizen on all issues. Examples are Washington (the state) voter initiative system and Senatorial elections post-1913 (they were originally elected by state legislature. see http://www.senate.gov/artandhistory/history/common/briefing/...).
