那么，编写自己的网络抓取工具怎么样呢？它会递归抓取所有的twitter页面，分析他们的用户名源代码并将它们存储到你想要的结构中？

Twitter肯定会喜欢+1（或更好+5？）。

玩得开心！

Well, what about writing your own web crawler which willr ecursively crawl all pages of twitter, analyse their source code for usernames and store them into what ever structure you want?
Twitter surely will like that +1 (or better +5?).
Have fun!
