It would be nice to put in a users profile area a place where they can see all the posts they made in support, ideas, knowledge base, discussions and answers, listings, videos... submitted throughout a website portal.

Possibly to add with the gamification piece is a way to allow users to see how they have contributed.  A way for a user to search all of their contributions to a website to make it easy for them to go to things they may have favorited, rated and discussed to return to later and so on from one location that is easy to use.

Also could be a setting for if it is being used for a user profile or user groups or general page that displays latest content by they user, group or everyone (similar to what the journal can do but with more options to sort and manage).  I have had issues putting more than one journal feed on a page.  To do this it may take a few journal modules to make it easy to follow for a user.
