Hiram Enriquez, director of digital media at MTV Networks, has a saying that is worth repeating to those who want to start their own media: "Nobody cares about your blog."
It’s a way of recognizing that there are millions of blogs and other media competing for attention on the web. In other words, if you build it, they won’t necessarily come. You have to prove the value of your content to attract an audience, and you have to market yourself through social networks and search-engine optimization, among other strategies.
