What is this page?

Hey, I just clicked several links, filled in a few fields, and found myself here typing into this editor. What is this thing? Where am I? It says "blogger" up at the top, so this must be some sort of Blog thing. Ewww, Blog!

I wonder how it will format this stuff I'm typing. And what if I want an image? Well, my first attempt at adding an image failed, which is why you don't see an image right there. Try again?
It worked! Woohoo! Check out that graph. I made that in Mathematica. And then I made that link. That was easy. The buttons are nice.

I guess I'll click "Publish Post" now...
