Foursquare users have been tagging themselves to anywhere and everywhere they please over the years, but one feature many people have been wanting ever since the application was launched was the ability to check in your friends if you all happen to be at the same place. Foursquare has certainly noticed as over 90% of mentions typically include a person you're currently with, and today, they're allowing people to check in their friends. The process of checking in your friends is easy as you'll first check into whatever it is you and your friends are doing, then proceed to tap the “I'm with...” option to add people you're with.
