Foursquare is a location based social networking program you can use on your iPhone, Android, Blackberry, Palm Pre, or computer. People who use the program “check in” at locations such as restaurants, bars, stores, and tourist attractions. When they check in, they have the option of sharing their location with their friends on foursquare, Facebook, and Twitter.
If they want, they can also leave a “tip” about the place they are visiting. For example, if you look at the the San Francisco Museum of Modern Art’s page on foursquare, you’ll see that (as of this writing) 1,215 people have “checked in” (773 of them are unique visitors).
Some of the “tips” people have left about the SFMOMA include:
“Great selection of books and jewelry. Great place to buy gifts. You don’t need to purchase a museum ticket to go to the store.”
“Check out the Richard Avedon exhibit (until 11-29-09). He rocks the camera lens!”
“Head straight for the rooftop garden, stopping for some Blue Bottle coffee on the 5th floor. Admittance to the MOMA is free on the first Tuesday of every month.”
