After reading this story, I'm finally going to delete my FarmVille. I just ignored it for several months, but now it's gone.
He's only pushing this because he's running a parasitic company. Instead of paying to make his own site, he's pressuring Facebook to change and do it for him.
EDIT: Now that I think of it, Facebook used to have a sort of app bar. It was just a little thing at the bottom that could bookmark 6 apps, and now it's gone. I find it annoying, since you have to go back to your homepage to navigate. He might be onto something, but that's only because somebody else thought of it first.
