Steam Trading's emerged from the hot wet clouds of beta after more than a million in-game items were swapped in the first month of testing. Purchased in-game objects can now be bartered between all players of Team Fortress 2, Portal 2 or Spiral Knights and more games will be supported soon. The bigger news is that you can also exchange Steam gifts and extra copies of games you've got -- such as that spare edition of Half-Life 2 that you downloaded with the Orange Box bundle -- as long as they're unplayed. Hey, cash it in and go buy your avatar something nice.
