Results of Steam Treasure Hunt?

[FadedOasis]

From the Steam Treasure Hunt rules:

Winners: Sponsor will select five (5) winners by random drawing for each Treasure Hunt objective for each 48-hour period within 24 hours from the end of the period. Sponsor will select three (3) Grand Prize winners by random drawing by December 21.
No later than January 10, 2011, Sponsor will hold a random drawing for alternative entries received for each Treasure Hunt objective and for the Grand Prize drawing, using the same odds as applied for each actual regular drawing (determined by the number of regular entries for each Treasure Hunt objective). Sponsor will award prizes to each such alternative entry winner. Sponsor will contact each winner via email to the address registered to the winning account. The decision of the Sponsor will be final and binding in all matters.

Your lack of Google-Fu is showing. I searched "Steam Treasure Hunt" (no quotes), and hit the cached link.
