We all know people commiserate on social media. Millions turn to Facebook to post the upset of their days and the tumult in their personal relationships. In return, they get support and advice from friends and others who can relate.
The homeless, though, use tools like Facebook, Twitter and even email to set up and maintain what they call life-saving connections. A simple cellphone can be a vital link to support groups, employment and housing opportunities, and is a way to build a community out of the isolation, ruin and despair that accompanies homelessness.
