Want the best latte? Ask a real ghost in New York.

I can already get this experience as I walk through Little Italy, when restaurateurs try to lure me in with "specials". Unfortunately, the loudest most assertive people are the ones usually offering the worst meal for my money. Yelp's use of crowd sourcing and aggregation was the solution, not the problem.

There will have to be an algorithm that decides whose voice should be heard, in which case, maybe they can use a reputation system to make sure I'm not being gamed.

Sorry but if you're standing in the middle of a bustling city filled with cars, bikes and pedestrians moving with determination, the last thing you should do is transport yourself somewhere else with different sounds that mask the current ones. Not to mention how annoying it would be to have some guy standing in the middle of the sidewalk so he can hear about the magical time a 'ghost' saw Wallace Stevens carry a pair of socks out of Macy's.

Almost 100% OT:

I will visit NYC with my wife next month. It's my 12th or so time, but her FIRST!

I would love to give her an experience like this, with a real person walking us through Brooklyn, East Village, etc. What should I do to make it happen?

Seems ripe for geurilla advertisement.
