The CEO of the photo sharing site SmugMug has written a great article about how camera manufacturers rip off consumers by promoting the deception that a camera with more megapixels equals an increase in image quality. There are many people that I know that simply don't understand that it's not how many megapixels that are important, but the quality of the lense, the size of the sensor and many other factors that play into the image quality.

I just recently found Zooomr, a photo sharing website that is like Flickr, but it uses the Google Maps API so you can 'geotag' your photos and search for photos taken in a specific area. Sadly New Jersey doesn't have a lot of great photos taken in it.
