Mouse Loves Elephant: Storytelling: how to mash up an ancient skill

I propose a giant grid, something mashed up with Google maps or something. The website visitor can click on a street corner and add their own personal story or anecdote. Something similar to this already exists on the internet where the map indicates the bar or store or sightseeing attraction with a little info about it. I think there's also rock and roll history...yes...that's it. Now I remember, For example, it'll show the Blue Ribbon Bakery in teh West Village and there'll be pop up information that Jimmi Hendrix used to buy his fresh bread there. (If you know the website, please add a comment linking to it as I cannot for the life of me track it down on the internet)

I'm proposing something a lot more personal, something very texty and anecdotal. I think it'd give people a real behind-the-scenes look at teh city. People could post stories about where they met and hooked up with some guy or gal or their new york horror stories ("This is the corner where my friend Billy and me were mugged. Three guys came up to us with knives and one of them even had their girlfriend there and she was almost as aggressive as the guys. I just gave them everything and ran down Seventh Avenue! Billy was 100 metres ahead of me!")
