Foursquare has added photos and comments to its iPhone app. So now users can share an image and their thoughts with their check-ins, with the info available almost exclusively to a user’s friends.

According to Mashable, Foursquare’s head of product Alex Rainert “believes photos and comments will stimulate activity in and outside the application and better support the fluid exchange of information.”

The features will be coming to Android smartphones next week and Blackberry users will have it next month. Let us know what you think about the new features in the comments.
