It's like the difference between being given a wrapped present, or just the present in it's actual box. In one case, you know the size and idea of the contents. In the other, you have noooooo idea what's going to show up.
So, going like this:
This post contains a poem
Now, you can see the overall topic that is going to be inside. So if you didn't want to read a poem, you didn't have to. And if you did - you knew it was going to be a poem and were thus aware enough to decide you could handle it.
