If you don't already know about the Real Change newspaper, check it out:
They are a non-profit group that publishes a newspaper that explores issues surrounding homelessness and poverty in Seattle. From their site: "Our publication strives to create fairness, opportunity and community by covering issues that socially conscious people want to know about, from topics surrounding poor and homelessness, to stories about labor, the environment, public health and civil liberties (to name a few)."
You can subscribe, but I usually buy an issue from the woman who sells it outside PCC, even if I know I won't have time to read it. Their vendors are homeless and they buy their copies for $0.35 and sell them for $1 and are able to pocket the profit.
