Seeking advice on distribution for short documentaries

I recently launched a documentary web project about faith and immigrant communities in New York City:  http://faithinthefiveboroughs.org/  I'd love to get the videos out to a wider audience, and am trying to pitch them to WNET, POV, WNYC's website, etc.  Does anyone have suggestions for other ways to increase traffic to the website, and/or suggestions for a suitable distribution partner?  Any thoughts are very welcome!
