Despite an active following, Horvath's message hasn't quite made it into the mainstream. That'll change this Sunday, when Horvath will be taking over YouTube's homepage "with videos that smash stereotypes about America's most forgotten citizens."
Horvath's passion is palpable even via e-mail (his signature reads "Chief Evangelistic Officer, Do-Gooder and Loud Mouth"). Perhaps that's because he understands homelessness more than most Americans -- he lived on the streets of Hollywood for years.
The homepage curation comes at the midway point of Horvath's 2010 Road Trip U.S.A. He's traveling to 28 American cities, interviewing homeless individuals every step of the way.
