How many times have you gone onto Facebook to post something that you later regret others being able to see? Have you ever just wanted a small group of people to know about status updates/pictures that you definitely didn’t want your boss to know about? Now there is an answer to your problem: The Fridge.
The Fridge is a webapp that lets you create private mini social networks for you and your friends. Have a group of people you want to share stuff with? Invite them in and start sharing. Once you are done you can delete the group and all your stuff goes away with it. The best part is no one else can see the items in your group. No random Google searches, no phone calls from Mom yelling about that tattoo that you forgot to tell her about. Simple private social networking.
One use I am already thinking of is for things like trips, or parties. You take a trip somewhere with friends and you can save your photos to a Fridge group so only you and your friends can see them.
