The Photo Sharing Site That Doesn't Exist Yet

I ran across a post by Thomas Hawk about the ideal photosharing site. He is right on every count. I especially loved the geographic tags idea, as would anyone who likes to travel.

The value of photosharing (besides browsing randomly for entertainment) is in being able to extract a set of quality images that match a topic or idea. Image tagging, personalization and quality ranking within a large libarary of images would all contribute towards creating a versatile yet useful (in addition to enteraining) photo image web site.
