今天的新闻：除了Macworld的消息瘫痪了Twitter，还有一件重要的事情：Wikipedia 7 周岁了。从2001年1月15日Wikipedia建站以来，维基百科诞生了2,174,371个英文条目（我写这篇blog的时候），wikipedia.org是世界排名第九的网站（更具Alexa）。Wikipedia诞生了六个子项目：：Wiktionary，Wikibooks，Wikinews，Wikiquote，Wikisource和Wikiversity

现在Wikipedia有近250种语言，9百多万文章，150多万图片，一千万注册用户，75,000个作出贡献的作者。

WikiCharts显示当今最流行的条目是它自身的定义：什么是wiki？

Wikipedia同时也记载了当今文化，就像《哈利波特》、《光晕》等。Wikipedia还从侧面反映了事物的流行程度：例如Cloverfield条目的页面，在过去两周每天都有 261,000 PV。

还有更加好玩的：Wikirage。Wikirage可以跟踪条目编辑频繁程度得出：哪些条目争论最多。毫无疑问，今天争论最多的条目是MacBook Air

如果250个语言版本的Wikipedia是个恐怖的数字，那么其中有一个版本是最有用的：简写版(Simple English)：用不超过1500个英文单词描述一个条目。例如 Harry Potter 的全文描述是：

“Harry Potter is a series of seven fantasy novels written by British author J. K. Rowling. The books chronicle the adventures of the eponymous adolescent wizard Harry Potter, together with Ron Weasley and Hermione Granger, his best friends. The story is mostly set at Hogwarts School of Witchcraft and Wizardry, an academy for young wizards and witches. The central story arc concerns Harry’s struggle against the evil wizard Lord Voldemort, who killed Harry’s parents in his quest to conquer the wizarding world.”

简化英文版：

“The Harry Potter books are a popular series of fantasy books by J. K. Rowling. The character Harry Potter is the hero in the stories.

In the books, the fantasy is about magic. Harry Potter is born with the power to do magic. He soon discovers that there is a whole lot of magic people in the world, living unknown to most ordinary people. When he is eleven, he is invited to go to a boarding school for young witches and wizards. Each book tells about one year of his life at school, about the people that he meets there, the things that he learns, and his adventures.”

简写版几乎涵盖了完整版的所有内容。但是完整版有超过7000个单词。

恩，WIkipedia生日快乐！虽然wikipedia和传统百科全书相比缺乏权威性和准确性，还是毫无疑问Wikipedia是最方便的
