more about our discussion about the anonymity of presence online:
This site is a diving board for people who are homeless to begin using social media. It advocates the use of social media to give these people a voice in a community that is more apt to ignore them.
People don't often listen to people who "look" homeless, but because with social media they can blog/tweet/status update from their hearts and be judged only on the basis of what they say without being preempted by something else, people listen.
