Wiser has a great deal of social graph imbedded in the content - i.e. who created a resource, who belongs to a group, who commented on some content. It would be great to be able to search using this social graph (perhaps in combination with a recommendation functionality). I want to be able to find something based on the fact that a friend or a person or organization I respect is connected to it. This could / schold be part of a filter on the vizualize functionality.
