Flickr has found an interesting way to leverage the data from their community of users. When pictures are uploaded to Flickr, meta-data about the camera used to take the pictures is uploaded along with the the photographs. Flickr is now providing this information for anyone to view, while using it to drive traffic to Yahoo shopping (as most of you know, Yahoo owns Flickr).

I like their innovative approach to reusing the data; however, Yahoo is not as good at Google about distinguishing between content and advertising.

For example, the main part of the camera page prominently displayed at the top shows a “Featured Model” camera, which is actually an advertisement. In tiny light gray letters under the feature, you’ll find this small disclaimer: “Featured Model is a sponsored placement.” The idea is really cool, but credibility with users would be increased if Flickr / Yahoo flipped the approach to feature the content (which cameras are really being used) while still providing clearly delineated advertising from sponsors.
