Google+ 為何不完全開放邀請？
昨天在Google +上問該項目的負責人為何不完全開放邀請，其項目負責人已經給了答覆。我的問題：Thanks for you guys creating the great Google + project, but why do not you open the invitation system of the project completely?
通過翻牆門檻不大不小的篩選核心用戶群，保證G+質量。利於之後發展。以及與http://weibo.com、http://kaixin.com等垃圾區別開來。
Google +項目負責人之一Lea Kissner答覆如下：
Lea Kissner：湯海泉: Were working on it. 
Were using field trial as an opportunity to fix bugs and make sure that everything works well before scaling to the whole world. Writing an application is hard. Writing one that scales well to a large number of users is even harder, especially since large systems dont behave completely predictably. Rest assured that were working to open things up as quickly as we can.
1.邀請註冊可以讓用戶有良好穩固的關係鏈，建立自己的圈子。2.產品從第一個版本到逐步完善需要一個過程，通過小部分用戶的使用和反饋逐漸完善產品。
3.從性能角度上來說如果沒有完全成熟的產品開放註冊是災難性的。
先通過小範圍的邀請，提高核心用戶的質量，這樣大概能保證在開放使用時能有更充實優質的內容，也有更健康的社區氛圍吧
一旦過早地大眾化了，必然導致質量的下降
想起暴雪的一款遊戲，星際爭霸2，測試了很久很久，就是職業精神吧
