Windows Live Writer的Ping Server功能非常有趣，讓我不由得想起當初研究SEO得到的一點心得。台灣一個叫做部落格觀察的網站，參考一些搜尋引擎的計分標準，制定了一個排名的公式。這個公式大幅參考了Google、Yahoo!跟Technorati的排名與分數，大致上還是與其他的搜尋引擎掛在一起；不過話說回來，要自己跑crawler也太困難了點。
說到crawler，Ask.com就是想要我去作這玩意；我最近忙著寫研究的程式，跟Ask.com的interview只能延到三月；我一方面沒時間，一方面也真不很情願寫個三四個小時的程式去on-site，等三月多考完資格考再說吧。
下面是我蒐集來的一個Ping Server List，有興趣的可以自己取用，不保證這些link全部有效，不過大部分的blog ping server應該都在裡面。如果真的無聊的話，還可以試看看Ping-O-Matic、autopinger、pingoat等手動的website，不過ping太多次對自己的blog反而是不利的，這點自己心裡要有數。
