Hey, what a surprise to see you here!
You probably got onto this page by accident or out of curiosity, but I suppose you can't help wondering...
First, the rather mundane reason for its existence is that it was the only way to trick Google Sites into displaying a nice dividing line in the navigation bar – at least the only way I could think of.
Second, it serves as a secret entrance to the blog I'm planning, which is currently a sales pitch waiting to be rewritten into a proper blog article.
Happy reading!
