From Rizwan Malik:
Look - the newest social network for sharing cool things with friends and family.What's a social network?A competition for the most likes/followers?Posting 140 character rants about your cat?Sharing 500 pictures of your new baby?No.Look is a social network.Look is an app that lets you share links (to anything (even apps and iTunes songs)) and pictures with your friends and family. Recipients of a cool post can then group chat: no annoying notifications.Look lets you keep these cool things so you don't lose them in the future.
