This can work for some products but not for all. For example I rarely do a research on what movie to go to see. If it was not advertised somewhere (e.g.: trailer before another movie, a print ad in a bus stop) then there is little chance I will decide to go and see it. Same goes for applications, yes there are channels for ranking and rating them and most of them are subpar to say the least (with the system often being gamed or skewed because of often lazy users). I've come to know many of the services and apps I use through channels like podcast and blog advertising. When done right, ads can be enjoyable (for example they are the only thing worth reading in an in-flight magazine)
