Most of my career has been dedicated to communications, either in making tools for enabling it, or in trying to practice the art myself. My friends tend to be people of conscience, so they often question why I waste my time on activities that could be described as "marketing" or even as hype when there are much bigger challenges that my talents could be applied to.
Perhaps the best articulation of why I think communications matters is in this short TED talk by Rory Sutherland:
In short, Sutherland argues that we need to start to value intangible, emotional experiences and that marketing, communications and, yes, even advertising can help bring that about. By starting to place importance on experiences and appreciation instead of objects and consumption, we become more sustainable as a society while also becoming more creative as a culture.
A lot of people offered up criticism when I launched Last Year's Model, asking why I was just encouraging people to talk to each other instead of actually doing something. As it turns out, talking to each other is doing something.
