Here is an excellent blog post by Chris Brogan on the “why” of podcasting and new media. I find myself trying to explain this to many people every day and Chris has some great points to share.
What compels someone to blog daily? Why should one pick up a microphone and record themselves or others for hours at a time? Who are these people who turn their cameras backwards and film themselves? And why should YOU create personal media? Understanding that the readers of [chrisbrogan.com] are mostly already in this camp, maybe I’m just reinforcing the point. But then again, perhaps you know someone who’s questioning why they should bother creating media in some form or another, and maybe this will help them understand better what they can accomplish.
