What would it cost in terms of time and money to get a website along the following lines running, and perhaps more importantly, what do you think of my idea?

Have you ever taken a picture and when you looked at it, there were strangers in the background?

Have you ever been in the background of a stranger’s picture?

Wouldn’t it be neat if you could find the pictures you’re in and/or the strangers in your pictures?

What if there were a website where people could post:

1) Pictures of themselves in hopes that some stranger will recognize them from the background of a picture THEY took, and post that picture as a response, and

2) Pictures they have taken of other people, places and things which have strangers in the background who they don’t know.

Imagine the same thing only with videos.

Would you visit a site like this?

Do you think it could ever take off enough that people might actually make these kinds of links, or would the odds be too stacked against anyone ever finding a match?

What would it cost to create, set up, host and maintain a site like this, both in terms of time and money, where people would be allowed to post pictures of themselves or of strangers in hopes that someone recognizes them as a stranger in their pictures, or in hopes that someone recognizes the strangers in their pictures?

Would adding private messaging so someone with a potential connection could first contact the poster of the original picture add value to the site?

Would it add value to the site to have a function where people could browse the pictures and suggest links between two pictures which may both already be on the site, which contain the same person(s), but which had not yet been linked?

Would it be a nice feature to, if and when enough connections were made to put together sort of a degrees of separation collage/slideshow?

Is this a brilliant new social networking idea, or the product of me not getting enough sleep lately?
