v1 To me sounds more like a way to facilitate sharing. I suppose this could lead to fostering relationships between strangers but for example I would get immense benefit from just having additional/better photos for an event that another person decided to share.

> Your description of v1 sounds exactly like meeting strangers; am I missing something?

No, you never meet strangers. You get their photos, they get yours. You know nothing about them, except they are not too far from you.
