Yeah, it started off great when you just had profiles, no statuses, no news feed, no clutter.
And for the record, Mark Zuckerberg isn't a billionaire. Facebook is estimated to be worth $1.5 billion, NOT $15 billion like some early projections, and facebook is only making a few $100 million in revenue. Don't mistake someone with a great idea for someone with a great business mind. Larry and Sergey didn't have the business mind until they hired a CEO.
