Steamgifts should put a damper on posting bundle leftovers. Every time a new bundle is introduced, the main page is flooded with fifty copies of the same game.
I believe there should be a "Is this a bundle game?" question on the create page, It would be cool if we could filter those out.
Don't get me wrong, I'm glad for the opportunity to get at games I missed and the ability to boost my contributor status, but I have to sift through twenty duplicates to fond the next item on the list.
