Tweens (10–14 year olds) in Estonia and Sweden were interviewed about their experience and understanding of gender construction on social networking sites (SNS). Our interviews indicate that peer culture is the most important dimension and a source of inspiration for the young when writing their identity online. Gendered norms and values are prominent in these activities, especially in the manipulated images being produced by the tweens. The latter practice is most explicit among the girls, especially when it comes to photoshopping. Our findings suggest that both girls and boys are well aware of what images are acceptable to publish as well as how to act and pose in front of the camera.
