After the relatively massive success of the Microsoft website "How Old", creator Mat Velloso decided to return with another. This release goes by the name TwinsOrNot - Twins or Not - and it'll help you decide whether or not you and a friend are actually secret twins. Velloso is a Microsoft man, developing this website for the greater good of Microsoft's Face API, showing developers how easy it is to make it work for them. Velloso knows what the people want. They want creepy photo uploaders.
