If you watch the advertisements and can actually act on said advertisements all is well with the system. However, if you have zero spending power, no influence and miss the ads... all is not well.
When are we going to say; What the hell is the point of this? Users "using" something doesn't make it profitable unless they are willing to pay you for it. Furthermore, advertising IS NOT working. Look at retail, malls AND name brands... Horrible performance for the bulk of recent memory.
Not trying to come across as snarky, but trying to setup an easy analogy :).
