[網路] 關於MSN Live Messenger的統計數據

前幾天看到一篇文章，是MSN和LIVE MAIL的經理(Group Program Manager for Windows Live Messenger and Windows Live Mail)所發表

其中揭露了一些平常Google不到的數據，覺得滿有參考價值的就先記下來

---

• Messenger 每段會話的平均長度為9-11 分鐘 (Session)
• 大約對話的 59%是 5 分鐘以上，超過 20 分鐘的約 10 %
• 每月有16 億個會話超過 30 分鐘
• 人們每一個月使用 Messenger交換 照片3億8千萬張；一年超過 45億張照片 （其中使用 Windows Live SkyDrive 和 Hotmail 的傳遞照片每月數以億計）
• messenger 使用者每個月有 2億3千萬的視訊對話
• 平均語音會話長度約 18.2分鐘
• 平均視訊會話長度約 13.3 分鐘
• 超過 1 小時 的視訊對話有 9% ，語音對話有13% 
• 依照地域性的不同，國際語音以及視訊對話的使用狀況也不同。13%的巴西人與國外使用者進行語音與視訊對話，西班牙和德國的使用者使用 50-75% 的時間在遠距語音、視訊上與他們的朋友與家人對話。

 而其中有一段我也覺得特別有意思

This is a very simple feature, but is really important to keep conversations flowing naturally.

In the real world, you typically wait until your friend is done talking before you answer. It’s a very basic social contract. Without a typing indicator, IM conversations feel unnatural, and you and your conversation partner are constantly “typing over each other.” But too much real time information loses the advantages of a written conversation, where people can choose their words carefully, or start a thought and then change their minds and cancel it.

Rather than show you every character I type as I type it, Messenger tells you "Piero is writing…" so that you can wait for me to finish my thought before you jump on to the next topic. You cannot tellwhat I am typing until I press Enter. Through extensive user testing, we found that this strikes the right balance between privacy and keeping people engaged with the conversation.
