That being said, a magazine with stories chosen and/or written by the homeless, disadvantaged and ones attached to the "street life" as well as sold by that same group, would have a very positive impact.
Mostly because mainstream news (which includes your cities paper) is a wash of bullshit to distract your mind from reality, and newsworthy stories are often suppressed....like the fact that police take more time to respond to a murder than to kick a homeless person out of a 24/7 coffee shop...
I believe that one city in particular in Canada that would benefit from this is Victoria B.C.
I was homeless there for only a few moths, but I learned alot in my time their.
There was a guy from Calgary who was a good freind of mine known as "star-man" and he had a good relationship with the media, it was his plan to startup something similar.
