I fell on this blog the other day. It attempts to register every single website that has anything to do with 2.0 and photography. It is amazing to see how many useless applications are out there, mixed with potentially good idea. Most are Flickr’s wannabees, some seem to have moderately good business models, others make no sense whatsoever.
I did not have the time, nor the patience to review all of them. I’ll let you do that.
