The Quag interest graph is also able to understand what users are interested in, but also the extent of their interest in a topic, and whether their contributions on Quag to the topic indicate they are experts on it or would simply like to learn more about it.
Quag uses an interaction model that is different from the traditional Questions & Answers (Q&A), with the aim of offering greater scope for interconnecting people and thus allowing them to develop complex discussions, also by using multimedia elements such as images, videos and links to web pages.
