oh absolutely agree that not everyone is on facebook.. (for example - all my younger cousins are only on myspace :P) (Also - I'm coming from Aus - where fb is #2 after google ahead of youtube, myspace, ebay, etc -- so my sample size may be biased..)

My point wasn't that there aren't millions of internet users who aren't on facebook - it's that there aren't millions of internet users who WOULD BE INTERESTED IN SHARING PHOTOS who aren't on a social network of some sort..

are you insane? Why do you think most people take photos? To remember and share memories.

How do you think most users of digital cameras share photos? via email? Print them out? You know, and I know those two methods are rubbish.

Even if there isn't millions of users - you'd only need a few thousand to get your startup rocking.
