I love the concept behind InvisiblePeople.tv. On the site there is a warning/disclaimer that says "CAUTION: Some content may be offensive. Our hope is you'll get mad enough to do something."
The purpose of InsiviblePeople.tv is to bring attention to the plight of the homeless and encourage people to take action in their local communities. The site gives the homeless a face and a voice.
From the site's about page:
The purpose of this vlog is to make the invisible visible. I hope these people and their stories connect with you and don’t let go. I hope their conversations with me will start a conversation in your circle of friends.
After you get to know someone by watching their story, please pause for a few moments and write your thoughts in the comments section, or maybe email them to a friend and link back to this vlog . By keeping this dialog open we can help a forgotten people.
You can get involved in InvisiblePeople.tv's project by participating in their road trip or making donations. All the information you need is on the site on the Road Trip page. If you've been active with this project or if this post motivates you to take action, please let us know with a comment.
