Location-based dating is FINALLY hot, Hot, HOT!
Some ideas take a while to come to reality. Urban Signals is a New York-based company whose iPhone app notifies you when compatible singles are nearby and would like to meet. The iPhone app is free to download but requires a monthly subscription after the first month.
While some suggest that this was only a matter of time, this has in fact been happening for at least eight years.
Back in 2002 I wrote about proximity dating in my book Living Networks.
