The addition of the quest system and various achievements here on the site has really increased my participation. These improvements have made GiantBomb itself into a game.  So meta. 
  
It's funny to think that back when Jeff had just been let go/quit  from GameSpot, he had this little blog with various game reviews. He'd offer updates about himself and the site.  Before the site went into full effect, I talked to him at a Kotaku E3 party in downtown LA, and complimented him on his small endeavor (it was an honest compliment, I just assumed he was taking time off). Little did I know how huge his plans were! One day, this site just blew up! (pun intended?)
