I have written before about business' clever usage of free wifi networks (example of Philz Coffee who lands users on their Facebook Page). Here is another good one. I am in the lobby of a NYC Kimpton Hotel (early for a breakfast). To access the wifi network, I can either pay for a 24-hour access OR register for their rewards program and access for free. Which do you think I chose? And what's in it for Kimpton? A new loyalty member and all that comes with it: information, offers, etc.
