Aaaaaarrrgh! That's the whole negative point. It's taking social networking away from the social concepts and turned it into a marketing tool. I can understand how marketeers look for new markets but the problem is they attempt a takeover. Look at blogging, once the home of the crofter in Scotland or the housewife in Hounslow, now all you see are attempts by nearly everyone to monetise their blog or just use it as a feed to their ecommerce store. The more the marketeers use social networking to push their products the more people will look for alternative means to socialise.
