Mobile Magazine editor Christopher Null tells public relations firms representing wi-fi and mobile entertainment accounts what type of stories he looks for, why they're more receptive to pitches about MP3 players, digital cameras, cell phones or any other type of gadget or technology that lets people become more mobile, than they are to notebook computer pitches. Null says the magazine regularly covers wireless, wi-max and G3 cell phone technology, and also discusses the extraordinary growth of desktop, notebook wireless access, why they rely on evergreen feature stories, how blogs impact his perception of news, how technology is disrupting news cycles, the best way to contact him with story pitches, the importance of product reviews to his publication, why product specs and high-res images should be available on a company's Web site and why podcasting is here to stay.
