Via this tip from Poynter Online I came across this Zip Code Index that arranges news articles by their zip code of origin.

Seems this is an opportunity to niche your products.

How?

Well they seem to allow you to upload your own links to news by zip code.

You could use a free service like google trends to best target zips to your quips.

Then write news related to those zips and your niche then upload the link.

Ummmmm.....
