@Angle No, you don't understand, there's no good or bad algorithm. As soon as you deviate from "reverse-chron", you'll have a change of culture because there will be something to optimize against.

On the other hand, you can't optimize for "reverse-chron", except posting at the time you expect your audience to be awake, but that's about it. No content change will affect whether your post will make it to your followers' timeline. And that's a good thing.
