google今天宣布说：

Today, we’re announcing the completion of a new web indexing system called Caffeine. Caffeine provides 50 percent fresher results for web searches than our last index, and it’s the largest collection of web content we’ve offered. Whether it’s a news story, a blog or a forum post, you can now find links to relevant content much sooner after it is published than was possible ever before.

从此段公告中我们可以得出：
1、Google Caffeine可以使google索引网站的速度提升50%或者更多!
这一点百度同学要努力学习！要树立正确的“拿来主义”观点，向更优秀的同学学习不是耻辱！
2、对新内容的抓取速度大幅度提升
google举例故事、博客、论坛；不过这些都是有contents的pages，B2B、B2C的站点类contents很少的页面的收录会否有改观呢~ 期待其效果；
