你可以对Facebook提出很多合理的批评。按时间顺序排列的新闻源的死亡不是其中之一。

我明白了：你过去常常在Facebook上滚动，直到你不再看到新事物。这很简单，而且有一个内置的停车点。你对自己看到的东西有一种控制感，而且你从不错过任何东西。

但它再也不会回来了，而且有充分的理由。本埃文斯的一篇引人入胜的文章，发表在本-埃文斯网站，概述了按时间顺序排列的feed需要消亡的原因。基本上是数学。

每隔几年就有200-300人成为“朋友”的情况并不少见，根据Facebook的数据，结果是平均每个用户的朋友每天至少发布1500件事情。埃文斯利用这个数字进一步探索：

If you have 1,500 or 3,000 items a day, then the chronological feed is actually just the items you can be bothered to scroll through before giving up, which can only be 10% or 20% of what’s actually there. This will be sorted by no logical order at all except whether your friends happened to post them within the last hour. It’s not so much chronological in any useful sense as a random sample, where the randomizer is simply whatever time you yourself happen to open the app. ’What did any of the 300 people that I friended in the last 5 years post between 16:32 and 17:03?’ Meanwhile, giving us detailed manual controls and filters makes little more sense—the entire history of the tech industry tells us that actual normal people would never use them, even if they worked. People don’t file.

文章的其余部分说，即使是按算法排序的feed也开始变得势不可挡，并推测网站已经超越了它。它很值得一读，所以去看看吧。
