Google的CEO施密特说：

Google鼓励天马行空式的创新，每位员工都有规定的工作时间，干自己感兴趣却又与正在进行的工作没有什么关系的研究，相信你在工作时间里正在为公司的未来寻找方向，并有权召集自己的开发小团体，依靠这种平等和信任，Google获取到了源源不断的创新技术和产品，而每位员工也在这种氛围中寻找到并实现了自己的价值。

百度的CTO刘建国说：

我们不会做稀奇古怪的产品，我们判断做不做，主要是从网民的需求出发的，我们会分析网民关注的东西，网民喜欢要什么样的服务，把这个抽象整理出来一个产品。我们不会做一些用户不会用到的，但是用起来非常酷的东西，我们认为这个东西没有价值，产品必须要给网民带来价值，这样的产品我们才会做，而且这种产品的影响面是非常大的。

创新的战略差异如此之大。创新的动力来自哪里、怎样产生？你为所有网民还是为你的用户服务？用户是使用者还是参与者、共同开发者？除了数量之外，用户的深度价值在哪里？Yahoo!为什么要把“用雅虎用的最深的用户”作为两个核心目标之一？技术强劲，且市场占有率曾高达7成、远高于Google的AltaVista，转型门户为什么会失败？

忙得大脑缺氧，昏了。有兴趣的请留言，呵呵。

From time to time, we run live experiments on Google — tests visible to a relatively few people -- to discover better ways to search. We do this because there’s no good substitute for understanding how real people, in real-world situations, actually operate. Theories are fine, but “improving the user experience” really happens best when we understand what people do online.



So to learn more, we sometimes randomly select a group of people to see a possible improvement to search options. Or we may select a group of people and try out a new element while they're searching. If you ever wonder why your Google site looks slightly different from that of the person sitting next to you, this is why.



We are currently testing new ways to refine searches so that, for example, a search for jobs might offer a choice of job location or function, rather than forcing you to continually narrow the terms you type in to a standard Google search.







We’ve run another test to learn more about how people navigate to find the information most relevant to them: how you might find image search or information in Froogle, for example, when that might be just the thing you want. Here’s how that one looks.







And we test ways to enrich web results, such as by offering a "Remove Result" option that would omit particular results from future searches if you decide they’re not useful. You'll see this feature if you're already signed in to a Google service when you perform your web search.







There's no set schedule when we'll roll out these sorts of new ideas (if at all), but these tests help us to improve your search experience.



p.s.: Google is also active in CHI, the major organization on user experience and usability. We're participating in the annual conference this week in Montreal. More here.
