The Internet has replaced the ancient yellow pages. Not convinced? Just take a gander at how many Web services there are that try to let you search for a service or an establishment. Need a plumber? Check. Need to call a restaurant? Double check. But Internet services can provide more than what static paper can contain, like more detailed information and even customer reviews. That is the kind of convergence of information that Facebook is trying to harness with a prematurely outed "Professional Services" website that aims to connect netizens with the business they are looking for.
