On CNN.com, Valerie Street has written an article about Mark Horvath. Horvath goes around the country interviewing homeless people. Street’s article discusses the path that led him there. It notes how social networking sites like twitter and facebook can help bring an awareness to these types of social issues. Click here to read her article.
Also, if you want to see some of Horvath’s interviews, I strongly recommend you check out Horvath’s website (invisiblepeople.tv) or his youtube channel. (The videos download a little faster on youtube.)
