In the 2010 versions of SharePoint Server and Foundation, you could enable user conversations by adding a discussion list to sites. SharePoint 2013 becomes more social by adding new Community Sites and Community Portal templates. Community Sites provides a forum for structuring and encouraging discussions among people across your organization. For instance, you can deploy a site for members of an individual business division, or fill a community with email messages from a distribution list. The Community Portal is enterprise site template that enables users to search for SharePoint sites (or groups of sites) that use the Community Site template.
