There are several other interesting looking papers, including Zuckerman's Linear Degree Extractors and the Inapproximability of Max Clique and Chromatic Number, Ambainis, Spalek and de Wolf on Quantum Direct Product Theorems and Charikar, Makarychev and Makarychev with Near-Optimal Algorithms for Unique Games. I can't find the latter online but here is the result from a talk abstract.
We present new approximation algorithms for unique games that satisfy roughly k-ε/2 and 1 - O((ε log k)1/2) fraction of all constraints if 1 - ε fraction of all constraints is satisfiable. These results show limitations on the hardness bounds achievable using UGC. In particular, they disprove a stronger version of UGC that was conjectured in a recent paper. Somewhat surprisingly, even a slight improvement of our results (beyond low order terms) will disprove the unique games conjecture.Many more interesting papers, be sure to look the list over yourself.
