The competition has just reached the halfway mark and the best entries have outperformed Elo by over 8 per cent. The leader is a Portuguese physicist, followed by an Israeli mathematician and then a pair of American computer scientists."

Glicko isn't designed to take advantage of all the information that's available in this competition. To calculate your new Glicko rating, you just need the Glicko ratings of both players + the result. I bet all serious contenders in the competition use the whole history somehow. (I talked with one who uses a decayed history scheme; he beats Glicko).
As to the leaderboard, it's really not so clear. Almost certainly, some of the contenders are accidentally overfitting to the leaderboard test data.

Even for Slashdot it seems...
