Joke or not, I have to point out that just because someone's screen resolution is 2560x1600 doesn't mean they have their browser that huge. Personally, my browser is never wider than 1100px. I do usually go as tall as the screen, but on a small laptop...

There's a mobile version of the blog, though (without the massive header/footer.

Even #newtwitter gets this wrong. Space jumps down a page, all right, but one of the unread tweets hides behind the black header.

I haven't looked into this, but if anyone has a fixed position header on their project, they should look into overwriting the space bar action readability-style and calculating how far to jump down.
