Mark Horvath is at it again. The founder of InvisiblePeople.tv has put that Pepsi money to good use and launched WeAreVisible.com, a site that connects homeless people to social media.

I can see folks scoffing already—why do homeless people need Facebook?!—but those are the folks who don’t get the power of social media. Those are the folks who don’t realize that Mark Horvath has been doing this since 2008 and funded two cross-country trips with the power of social media. These are the folks who don’t realize the power of having a voice.

Homeless people are often powerless, voiceless and invisible. But they’re not helpless. WeAreVisible.com educates them about tools that can make them visible again.

And it works. The site includes stories of homeless people who have been empowered by social media.

I love seeing Mark in action. I just wish my InvisiblePeople.tv book was out and raising support for efforts like this. Soon. The book is so close.
