Blog on for Swerdloff My colleague Craig Swerdloff, who runs our Postmaster Network lead generation business and is one of the smartest people in the online advertising business, has started blogging. Of particular note is this post, in which he talks about the concept of explicit vs. implicit consent in advertising. His thinking is a lot like some of the things I’ve written about in the past, like the New Media Deal and the We Media Deal. The bottom line is that advertising has to be valuable and relevant for end users — and properly/carefully delivered. Welcome to the blogosphere, Craig!
