This is a common tactic I see on Slashdot: "How can Slashdot be praising x when they usually say y?"
The folks claiming that the "hiatus" is a denier hoax are not necessarily the same folks who published this paper.
Furthermore, the argument is not that "hiatus" is a denier hoax - any fool can see temperature readings have been flat in most measured areas. The counter-argument is typically that the Earth is really big and that surface measurements alone do not necessarily represent the amount of heat absorbed by the atmosphere. Where all of that heat has been going was where the speculation has been, with the usual supposition being "the ocean" or "the poles".
