Oh yeah, it's going to be awesome. And more work. Basically, you can have your entire website inside Facebook, too, on a page. Technically, it will be "better."
Facebook wants to be the web, replacing Google, which means they want to let you do everything you want to do.
The question is value. You have a website and email network. You Twitter. And you do a basic Facebook program. Why are you working to help Facebook built out their network? Isn't it enough that we work for Google, we need to work for Facebook, too?
The answer will be, for some, no. For others, it will be yes, Facebook works.
