Is there any formal and direct interaction between Designer and end-player??

Is there any formal and direct interaction between Designer and end player in video gaming industry ?.If so, can any one explain me how the relation works in the industry ?
This is all about an idea of creating a community and process between Design team and end user/player in order capture the feedback formal way on released games and demos.  This data can be helpful to maintain the history of ideas shared by players and their feelings and game play experiances and this data can be used along with sales history during analysis of concept/ idea. Also can be useful to take the game design in very different angle.
There are other ideas of formalizing the feedback templates depends up on the game genere and type.
Any comments are welcome.
