Social Networks are ways of representing formal links between people. We often make it explicit using befriending mechanisms but their are also implicit methods, like if two people published a similar paper together. On a forum people post information from a variety of sources. The similarity in the sources people use forms an implicit link between them. Other types of links could be similarly categories and topics of interest. Another type of similarity is the likelihood two people will comment on the same thread. This could form another method of creating implicit social networks and threads could perhaps be sorted by relevancy based on the number of people with similar interests who comment on it. In the future it is suggested that social networking tools will be the primary method for us accessing information. Currently social networks are relatively primitive with news feeds being filled up with junk put out by apps and trivial comments. However, there is a wealth of network information that could help us better sort and filter which information we find relevant and which we don't. To list these again: like systems rating systems shared links of interest (similarities in common sites and such) who started the thread who commented on the thread external links Sorting though all this information to find an optimal method is an interesting challenge.
