I don't remember, to be honest with you. I just remember seeing a similar concept on some blog a long time ago. I was posting my own shuffles on my own before any of this - which is really a bit more comparable to what the Onion is doing - but I know that I wasn't the first to make it competitive.
We've ONLY been doing iPod Wars for six months???

And I initially thought it was lame? Now I spend hours shuffling HTML to make attractive scrollwheel posts?

To quote myself, LAME. ;)
It's kinda funny, isn't it? You were, like, adamantly against the idea. And now you're my partner in crime. Dance, monkey, dance!
