From one side, it is exactly what Facebook should be better at than any other company; targeting specific people by interest and location, and networking that via the social graph. If my wall post provided free advertising for a company when I purchase a deal, there is a higher chance for my friends to consider the deal. On the other hand, Facebook has done a remarkable job not trying to become the Google of the internet. For instance they seem to have left Zynga alone to make games; where as Google has tried to buy (DoubleClick) or copy (Buzz) every product which came along in a niche that they hadn't reached into yet.
