After Apple SVP Eddy Cue tweeted a couple of Foursquare check-ins, rumors spread that Apple was talking to Foursquare about using its data for local search.
While Foursquare users can make their check-ins private or friends-only, the tips they leave are publicly viewable.
Cue had a really bad experience at Il Fornaio, a well-known Silicon Valley restaurant.
"Food and service were horrendous," he wrote.
More his style: the homey diner food at Squeeze In, a restaurant in the ski-resort town of Truckee, Calif.
Those kind of tips, as well as information about how frequently users check in to a particular location, could help Apple improve its maps—a business Cue has been in charge of since the ouster of former mobile-software chief Scott Forstall.
