Facebook. Their website is designed as if it was a graphical user interface, like an operating system. They have their own colour scheme, icon set (style), formatted blue and grey buttons, lightboxes, their grid layout for how they lay out the content, the box that shows your face when you're writing a comment.
It's like an operating system in a way. If Facebook was out in the 1980s, its interface would be enough to grant it to have an arcade/kiosk machine for it.
What's an assertion, and what should I type in?
Compesh is a question and answer (and debate) website, so before you make a debate, you better learn what an assertion is. I suppose you already know what a question is, and that you've typed it in the box. ;)
An assertion, is basically a statement you can make, that is either true or false.
Richer people have better health.
The question for that would be, Do richer people have better health?
And don't forget to make your assertion, match your question.
