Does technology isolate us?  Or does it actually foster its own unique kind of community? That's the big question the documentary 'Craigslist Joe' tries to answer.

Joseph Garner, the film's director and protagonist, ditches all of his money and possessions -- save a laptop, cellphone, toothbrush and the clothes on his back -- and attempts to live for 31 days through only the kindness and generosity of folks he meets through Craigslist. Check out the trailer for this Zach Galifianakis-produced film.

As the cynics will quickly point out, people are going to be much nicer to you when there is somebody filming everything you are doing. (A trick beggars would be wise to utilize) Nevertheless, it is an interesting experiment.

How long do you think you could last using only the goodwill of Craigslist for food and shelter? You can find out how long Garner did on August 3rd, when 'Craigslist Joe' hits theaters.
