I always had this in my mind even before reddit became a phenomenon. What would happen if all the popular forums are combined in to one? like a social network without changing the way of how they work. If forums are integrated, we would have so much of user generated content and lot of knowledge sharing happening. We would be a tough competitor for the current social networking sites as well! Considering lot of customization and filtration are done before combining them to a single network.... I know people prefer forums the way they are but i am just curious in knowing what others think regarding this.
