Most people have never walked down the street and looked for homeless people - most look the other way. But not Mark Horvath. A former Hollywood insider, Horvath has been a drug addict, con artist and, for a brief period, homeless. He says he's left that life behind, and these days, he's drawing on his dark past to inspire his Web site - Invisiblepeople.tv. The site is a collection of YouTube-length video profiles of homeless people he's met across the country, and it's become a surprise hit in social media circles. Horvath's style is simple and effective: Let people talk. It's personal for Horvath. Fifteen years ago, he was homeless. He had been fired from a six-figure salary job at a television syndication distribution company. He dabbled in drug dealing and credit card fraud, but neither venture paid very well. He found help, and God, at a faith-based shelter. He cleaned up, moved to the Midwest, and worked for a televangelist. Horvath insists all the money raised goes right back into the Web site. Chris Brogan is the author of Trust Agents, a New York Times bestseller about social media. He says Invisiblepeople.tv marks a new way of supporting a social cause - not through some big non-profit, but directly through one person doing one good thing.
