I think you mean 'News Feed', not 'wall'. Wall is the old name for your page. They are now called Timelines.

And Eurasia has always been at war with Eastasia? I really see no need to let facebook control language like this.

Huh? It's the name of their site feature. Someone has to call it something so we know what we're talking about... that's the basis of language.

We all knew what the greatgrandparent was talking about when he said "wall". I see no reason to "correct" him just because facebook have decided to call it that anymore.

Okay, but... just to help you out a bit... the News Feed was never called a Wall, actually. One is about you, the other shows posts by others.
