Craig Newmark started Craigslist in 1996 and runs it from a small office in San Francisco. It is now a free online notice board in 50 countries around the world.

Craig Newmark is not the only one building an online community. Jimmy Wales started Wikipedia. Wikipedia is an encyclopedia that anyone can write for. It was started in 2001 and it's available in 285 languages. It has 100 times more information than the old paper encyclopedias. But anyone can change pages on  the site and means new information is added  as soon as things happen. So next time you talk to your friends, buy or sell something online, think about how one good idea change people's daily life.
祝学习愉快！
