wow....pretty cool BT
I was at least thinking along the same lines a year or so ago
i "checked in" to my Facebook at an Italian Restaurant
the older guy waiter asked me what I was doing
i told him I was "checking in" on my Facebook
& everyone on my Facebook friends list would see I was eating @ his restaurant
he brought the mgr over....and I explained how it worked
and if they could get more people to "check in" on Facebook
that they would get their name out there to a lot of people
and basically it would be no cost advertising....they were
really unaware of the "check in" feature on Facebook & they
really liked the idea of spreading their name for free....
so they brought me a free Tiramisu dessert.....
I get a free dessert and these kids get rich! ....lol
