"Fourteen years ago, Mark Horvath was in crisis. The former exec was living on the streets in Hollywood, California, where for a dollar he let people take a photograph of his pet iguana, named Dog... Horvath returned to Hollywood Boulevard, this time as a featured speaker at the 140 Characters Conference, a Twitter-inspired gathering attended by movers and shakers in social media. Horvath told the audience how he uses an arsenal of social networking sites -- Twitter, Facebook, Whrrl, MySpace, YouTube, Vimeo and Flickr -- to illuminate the plight of the nation's homeless."
On Twitter, he has a combined 10,000 followers to his two streams, @hardlynormal and @invisiblepeople.
