Traditional social networks socialize around the contents that have uploaded to these sites and discover interesting contents uploaded by others. In this demo we aim to explore the idea of activity-oriented social networks. We design a novel social networking site called Dig-Event (Do-it-together Event), where people are able to share events through calendar, while discover interesting events shared by others. Our demo has been inspired by previous research on calendaring and popular social network applications like Facebook and Google+. It allows users to share their activities to the customized social circle, conduct events by selecting activity-based gadgets. The features of event recommendation and integration with existing social networks further boost the event socialization experience
