Shouts are mostly used as a way to tell people what you’re doing or to provide an explanation of why you’re at a particular venue. You can also use them to note something interesting about the venue or to make a shoutout to someone who’s there with you. Here are a few examples:
- Happy Birthday, Mike!
- Nothing beats watching @johncmayer play live!
- Ran into @dens in the men’s room!
- Shortest line ever to get in tonight
To attach a shout to your checkin, just type it in the text box on the check in screen. To make a standalone shout, use the “shout” button in your mobile app and type your shout in the text box. Your Foursquare friends will see your shout in their list of friends’ locations and you can optionally publish your shouts (either checkin or standalone) to Facebook or Twitter.
It’s common practice to call out people in your shout by their Twitter username. When you share those shouts with Twitter, they’ll see it on their @mentions screen. Your history page will also have a pop-up when you hover over their name, showing their avatar and other relevant information from their Twitter account.
