最近tag很火。在此说说我的看法。
tag并非高深的东西，技术上有一些难度，主要集中于海量数据的性能压力，但并非太难。
我的看法中，tag类似于关键词+分类的集合体。比起现在应用tag较多的网摘，邮件，照片，我认为人更适合应用tag。
各种object中，文字最容易检索，tag的意义不太大，邮件加上tag的意义大了一些，照片意义更大，人的意义就非常大。越是不易检索的object，则越是适合采用tag。广义来说，名片就是一种tag集合，但范围窄而且局限性强。
互联网时代，找人的需求比以往更大，人在互联网上成为一个个群落，属于哪个群落，就会有相应的兴趣相投的朋友。emule上面会看到这样形式的用户名：[chn][verycd][mop]xxx ，这就是tag了。如果能对这些tag进行处理和提供服务，相信很有意思。
