Why doesn’t Facebook integrate with something like Kodak Photo Gallery? Every picture should have a button that you can click that sends the original to a printing service. It would be even better if Facebook saved your credit card info but I think that’s going a little too far.
Think of all the nickels in commision Facebook (or MySpace) could get in that case. Sure you can save somebody else’s photo, but why not send the original to the company that will print them?
This seems like a huge lack of monetization on all social networking sites.
