Pull advertising is a necessity of distributed media advertising. As media have continued to fragment, I have seen arguments for Webs site publishers to play an active role in pulling the advertising content most appropriate for their site/audience. I have also seen arguments that the users viewing the advertisement are the most appropriate source of advertisement pull (after all, they are the end consumers). But, when the those publishing the content are also the target consumers for a given brand, such as is the case in social media, then the necessity of pull is enhanced exponentially.
