什么不是web 2.0?

(摘自程序员约稿文章中被删节的部分。 写的太多了,只好删掉了一些。为了不至于白写blog上发表出来,本文的全文在杂志公开发表后公布)

什么不是web 2.0?

       在讨论哪些是web 2.0的时候,很有必要搞清楚哪些不是web 2.0。有一些流行的技术是伴随着一批web 2.0的公司而成长和普及起来,但并不意味着你的站点支持一下这些技术,就变成了web 2.0 正如前面所说的“web 2.0是一种态度,而不是一种技术”,使用任何特定的技术都不能使你变成web 2.0.

       在各种各样的和web 2.0相关的文章和讨论中, 往往下面的这些技术或者概念和web 2.0纠缠在一起,让很多人为之迷惑。 下面的“XXX不是web 2.0其实准确地说应该是“XXX不是web 2.0的必要条件”。

       1Ajax不是web 2.0

       AJAX是一个老技术的新名字,但这个名字的出现出乎意料地造就了互联网上的一个新流行词汇,而且毫无疑问对这种技术的推进有相当的促进作用。 不过AJAX只是一种技术架构, 可以用于任何1.0, 2.0, 3.0,… x.0web. 千万不要认为用AJAX技术就是web 2.0.

虽然AJAX不是web 2.0, 但是如果合理采用AJAX技术将能大幅度提高web应用的可用性,用户的体验可以得到大幅度的提升。对于注重用户体验的web 2.0来说, 使用AJAX技术绝对是个不错的选择! 其实我认为使用AJAX技术对任何人都不是个坏的选择。Google, 微软等巨头们都纷纷推出基于AJAX技术的web服务,有理由相信,不久的未来大部分web应用可能都采用Ajax技术。

       对于迷信Alexa等基于网页刷新来进行排行的人来说,采用AJAX无疑是一种有害的行为。 采用AJAX带来的最明显改善,就是页面刷新必要性大幅度下降了。我们在 UUZone 2.0中大量采用了 AJAX技术,结果我们发现平均每个浏览session的页面浏览次数下降了30%~40% 但是,由于可用性改善了,用户浏览内容更流畅了,没有刷新页面带来的心理负担了,结果用户平均停留时间增加了20% 系统浏览量则在一个月内上升了200%

       2blog, wiki, RSS, 社会性书签不是web 2.0

       同样,blogwiki等作为时下流行的一类web应用并不是web 2.0. blog中,我们已经可以从RSS, trackback等技术中看到开放的身影,而且从blog的流行,我们看到了这些开放标准所带来的价值,和互联网个人言论带来的巨大威力。其实这种价值和威力还只是web 2.0的价值和威力的一些序曲,相信在web 2.0时代, 当开放和标准成为web世界的主流后, 释放出的能量和影响将是巨大的。

       这些应用本身不是web 2.0, 但一部分运营和提供这些应用服务的公司却是典型的web 2.0公司,他们所提供的服务,也是典型的web 2.0应用服务。原因非常简单, web 2.0是一种态度,并不在于你用什么技术,做什么服务。

       3、六度隔离假说相关的东西不是web 2.0

       很多web 2.0的服务都具有强烈的“社会性”, 何谓“社会性”? 简单来说是“人”与“人和人的关系”。诞生在50年代的六度隔离假说在2003年突然成了很多人的法宝,并且一度主宰了社交网络服务(SNS),幸运的是,六度隔离假说的迷信正在逐渐淡去,越来越的网站更加强调人,而不是空洞的六度关系。

Web 2.0所强调的社会性体现在很多方面,我认为关键在于:(1)以人为中心;(2)强调透过人和人的关系来组合资源; 因此这种社会性其实和具体的应用业务有很大的相关性。 

1、  web 2.0和商业模式无关

作为一种态度或者一面旗帜、一个口号,显然web 2.0本身和商业模式无关。 很多东西可以成为web 2.0, 很多人会宣称自己是web 2.0, 但究竟什么样的应用会火热,什么样的公司能成功,和究竟是不是web 2.0并无关系。 

Web 2.0非常强调业务的实用性, 但是并不是所有实用的东西都可以带来大把的业务收入。但是我们仍然需要知道一点:虽然不是所有实用的东西都可以带来大把的业务收入,但是没用的东西几乎肯定不能带来收入。

至于“长期beta版”、“轻量级公司”、“病毒式营销”甚至“逢年过节换logo”等等时下颇为流行的很多东西不是web 2.0, 虽然他们和web 2.0的确存在联系, 而且不少web 2.0公司选择了这么做。
