I live in Sleepytown, South Dakota. You live in Pigeon Fart, Pennsylvania. The odds that either of us will visit the other's domicile are nil. So why are you asking to be my friend on Yelp?
Pointless friending is pandemic on the social Web, but never to less purpose than when done in connection with a service that's all about local recommendations. If you will never eat, drink, sleep, or shop there, why do you care what I think about it?
The moral: If you're not local, you're just a yokel.
