Flickr - almost certainly the best online photo management and sharing application in the world - has two main goals: 1. We want to help people make their photos available to the people who matter to them. 2.We want to enable new ways of organizing photos and video. Part of the solution is to make the process of organizing photos or videos collaborative. In Flickr, you can give your friends, family, and other contacts permission to organize your stuff - not just to add comments, but also notes and tags.
