看了Mark 的專訪，由其中有些話又想起之前在思考的開放平臺的三個矛盾。後面收集些資料有機會和大家共同探討。
一、開放和封閉的矛盾
He said people have been trained to believe that there is a binary set of options concerning privacy and sharing of data: that some things are sharable and others are not.
"Take a photo album from a party," he said. "Unless you have specific tools to limit who can see it, then you won't share it with anyone."
有無相生，難易相成，長短相形。開放封閉是相對而生的矛盾共同體。
二、長尾和短頭的矛盾
"Developers aren't fundamentally spammy," he told me, "they want to add value around what they are enabled to do. So far they've been incentivized to get as many users as possible." He said the company is trying to shift the incentive structure to reward truly useful, trustworthy apps.
長尾的需求其實往往是被短頭的應用所滿足。
三、大象和螞蟻的矛盾
Data portability advocates might take heart in the fact that Zuckerberg wants to clean up the Facebook ecosystem of Zombie-throwing crap. The percentage of data worth making portable on Facebook is far from ideal today.
Data portability will not be viable anywhere until there are simple, granular and effective controls over user data and privacy. Facebook is in a good place to focus on solving those problems.
Facebook may have felt like the only game in town when the Platform launched, but things change fast and between the much broader OpenSocial and a fast expanding community of standards based developers - Facebook might soon find that it's sitting on the sidelines while everyone else works together to solve these common problems.
善舞的大象和螞蟻雄兵的博弈，後勢如何？
