Funny, I re-started using it again last year after ignoring it for several years. I've noticed I get lots of little freebies when I check in via foursquare. Ie., $5-$10 off a meal if i use my amex, a free dessert etc. Lots of local businesses seem to have these hidden deals but they don't publicise them.
