sodatea 看了几篇文章，确实存在争议

1.李彦宏于 gogole 创建前发表 Rankdex ，里面有提及到
>"Linking to a page means you like it. Counting these votes gives a
rating for a page."
>"Anchortext for the link usually summarizes the content. When your
query is straightforward, like “ Debbie Harry ” this becomes a highly
reliable way of finding a good Debbie Harry fanpage."
2.李彦宏借鉴了 algorithm of hyperlinks （超链接算法？）
>"The idea of associating anchor text with the page the text points to was first implemented in the World Wide Web Worm (Oliver A. McBryan, GENVL and WWWW: Tools for Taming the Web, First International Conference on the World Wide Web, CERN, Geneva, May 25-27, 1994)"
3.李彦宏 96 年曾经去斯坦福发表关于 Rankdex 的论文
>"Google PageRank was created in 1996 when the founder of Google was still in Stanford and exactly in the same year Robin Li gave a speech in Stanford about his algorithm. "
