Not surprisingly, this is not the first project to call itself Open Stacks. Although it does not seem to be active, the original "Open Stacks is an online digital library which houses references to key works that form the intellectual foundation of interface ecology." The linked page also explains what the author means by interface ecology. Be sure to take a look at Collage Machine, apparently another example of interface ecology, which forms a collage of the images found on the pages of up to five user-entered URL's. I bet it would be cool to combine some of the quality photoblogs for dramatic effect.
