Entrepreneurs, Homeless People, and Art

Greetings,
There's an interesting article in the New York Times.  It involves entrepreneurs who are helping homeless artists:

While many homeless people aren't artists and this won't solve everyone's problems, it does give artists an opportunity to sell their art.  Interestingly, the company that facilitates bringing homeless artists and art buyers together is not a charity.  This is a business model.  Artists are getting paid for their work and art galleries discover new talent.
