The article: Unpinned: Facebook Shuts Down Test Of Its Pinterest-Style Collections Feature reports that the experimental "Pinterest-like" Facebook gadgets have already vanished from Facebook.
That's too bad, because Facebook's plan was one that shunned copyright infringement, partnering instead with some companies that gave permission before their images were used in the user's "Collections."
The experiment was a flop.
This is interesting because many commercial outlets are trying to get their foot in Pinterest's door and some may be succeeding to some degree, like the Martha Stewart Living Pinterest page. It truly drives the point home that people love to infringe on copyright of artists to fill their image hoards much more than they do commercial images with implied permission.
This reinforces the notion that Pinterest owes its success to the unabashed copyright infringement that it facilitates, and that it probably wouldn't have gotten anywhere without it.
