While it takes some 900 employees to keep Facebook running, over 13,000 to support Yahoo!, and more than 20,000 to run Google, the user-edited and monitored online encyclopedia Wikipedia requires just 35 employees, and unlike all the other sites in the top sites worldwide (as ranked by Alexa.com), Wikipedia is nonprofit and runs almost entirely on user donations.
