为什么人人网把 iOS 客户端从原生写成 HTML5，Facebook 却将半 HTML5 重写成原生？
回复内容：
人人说，擦，你们不当屎了也先说一声啊！顺便再给大家看一个玩意儿 http://www.renren.com/timeline_waitinglist/index
说到底，人人就是非屎不可，屎也要像Facebook
说不定下一次就发布一个「人人客户端浴火版」，就改回来了。 两边都发觉到：
咦！貌似移动团队的那群家伙目前工作不太饱和嘛 Facebook 是改成了源生+html5 不是纯源生
源生->html5
节约开发成本和功能更新的问题 , 这样版本可以快速迭代而不必更新客户端,兼容性问题也较少
这时候更注重业务逻辑方面的问题
缺点是运行效率太低,不流畅, 使用体验的感觉是在摸网页而不是摸手机
这点有点类似为什么 "web开发大多选择动态语言" 的原因
html5->源生+html5
在主体功能基本固定了之后 , 框架更新不太频繁的时候 , 前端使用html5更灵活
这时候人力财力也相对宽裕 , 这时候更有精力思考效率方向的东西 , 所以可以着手来做原生化的骨骼.
这有点类似为什么"互联网公司成熟后 通常会把php , rails 的后端改成java / C++" 因为抄袭需要时间。 有个成语叫「亦步亦趋」。
对于有着复杂业务逻辑的 Web 社交应用的移动端，用 HTML 5 来实现再投机不过。
其次，我不觉得完全是押注 HTML 5 技术拖累了 FB 上移动平台上的发展，原生改写的 FB 固然在性能上提升显著，我个人依然觉得它不好玩。
再者，国内用户在应用体验上没有那么敏感，是 HTML 5 还是原生如果不给出显著的对比情况下，一般用户很难区分，君不见还有同学用 WAP 上人人么。
「没有银弹」，不投机取巧做出产品才是硬道理。 我只知道人人游戏最擅长的就是
