"In April 2011 Evan Spiegel stood up in a Stanford product design class to present an idea for his final project. It would be a mobile app, he explained, where friends could share photos that would disappear—forever—in a matter of seconds.2011年4月，伊万·斯皮格尔站在斯坦福大学产品设计班的讲台上为他的毕业设计展示了一个想法。他解释说，这会是一个APP，朋友们可以在上面分享照片，但是这些照片将在几秒之内永久消失。

"Everyone said, ’That is a terrible idea,’" Spiegel remembers. "Not only is nobody going to use it, they said, but the only people who do, will use it for sexting." A venture capitalist sitting in on the class said it could be interesting, if he made the photos permanent and partnered with Best Buy. Spiegel nearly gagged."斯皮格尔记得，“每个人都说‘这是个糟糕的点子’，他们说‘没人会用这个，就算有，也是用来发色青短信’。”一个坐在教室里的风险投资人说这会很有意思，如果他能让这些照片永久存在并且和百思买集团合作。斯皮格尔几乎要笑出来。（伊万·斯皮格尔：Snapchat创始人）

Amazon - we’ll sell books online, even though users are still scared to use credit cards on the web. Their shipping costs will eat up any money they save. They’ll do it for the convenience, even though they have to wait a week for the book.亚马逊——我们要在线卖书，即使用户们还很不放心在网络上刷信用卡。运费会耗掉他们省下来的钱。他们会因为方便而买账的，就算他们要等一个星期书才到货。

iOS - we are shipping a brand new operating system that doesn’t run a single one of the millions of applications that have already been developed for Mac OS, Windows, or Linux. Apple has to approve all of the apps, and it won’t have cut and paste to start with.iOS——我们在推出一款全新的操作系统，它没有运营任何一个已经在Mac OS、Windows或Linux上已经在使用的应用软件。苹果要认证所有的APP，而且它不需要从剪切和粘贴来开始。

Google - we are building the world’s 20th search engine at a time when most of the others have been abandoned as being commoditized money losers. We’ll strip out all of the ad-supported news and portal features so you won’t be distracted from using the free search stuff.谷歌——在大部分搜索引擎作为商品化亏损企业而被淘汰时，我们要建立世界上第20个搜索引擎。我们要剔除所有广告支持消息和门户功能，这样你就不会在使用免费搜索工具时觉得很烦躁了。

Firefox - we are going to build a better web browser, even though 90 percent of the world’s computers already have a free one built in. It’s based on a product that a single college student built.火狐浏览器——即使世界上90%的电脑都有内置的免费浏览器，我们也打算造一个更好的。这个浏览器基于一个大学生创造的产品。
