• Space is as pure a Web 2.0 play as you're likely to find and they've exploited user generated content and network effects to become the #1 visited site on the Web
• 

  • the key to web2.0 explicity leveraging network effects:
    inducing network effects==>value target(intent):community creation /growth ,process invigoratioon,fostering/harvesting innovation attention(esp.advertising)===>mechanisms:low-barrier participation;connection enablement;unique user-biuld data sources;small pieces,loosely joined applications as platforms syndication ;feedback loops==>connection types:content(blogs/wikis);people(social networks);group activities
• • my idea:i could find lots of good english pure blogs from the collection of chinese blogs
• The end result: If you have a million people visiting your Web site but you're not leveraging network effects with them (such as by letting them contribute and letting others see and respond to those contributions), then you're probably squandering the greater part of the value of that million person audience.  Along comes someone else who does exploit the network effects of their users.

• PageRank(网页级别)是Google用于评测一个网页“重要性”的一种方法。在揉合了诸如Title标识和Keywords标识等所有其它因素之后，Google通过PageRank来调整结果，使那些更具“重要性”的网页在搜索结果中另网站排名获得提升，从而提高搜索结果的相关性和质量。

• Google的PageRank是基于这样一个理论：若B网页设置有连接A网页的链接(B为A的导入链接时)，说明B认为A有链接价值，是一个“重要”的网页。当B网页级别(重要性)比较高时，则A网页可从B网页这个导入链接分得一定的级别(重要性)，并平均分配给A网页上的导出链接。  

   

  导入链接(也叫逆向链接)指链至你网站的站点，也就是我们一般所说的“外部链接”。而当你链至另外一个站点，那么这个站点就是你的“导出链接”，即你向其它网站提供的本站链接。

   

  PageRank反映了一个网页的导入链接的级别(重要性)。所以一般说来，PageRank是由一个网站的导入链接的数量和这些链接的级别(重要性)所决定的。
