IMAGES 2.0 - consolidated

This is one of the biggest categories. You could say that massive content sharing on the web started with photo album sites (remember Zing?). Flickr, coming from a simple text game, accidentally discovering photo content as an extremely sticky glue to build a community with, of course is the origin, benchmark & inspiration of many later Web 2.0 concepts.
In this category you'll also find quite some samples of initiatives to monetize content - B2C and B2B. Update 060812: Photo books, printed on demand seems to be the newest sub trend in this category.
Much more photo content in the category MULTIMEDIA 2.0.
