Sounds like cognitive dissonance is playing hell with their minds at the moment. The brain, when faced with evidence that contradicts a dearly held belief can either accept the new evidence or drown out the evidence by shouting the belief even louder. I'm guessing they're going to keep on choosing the second option for quite a while yet...

Glenn Tamblyn, I'm not particularly confident in declaring a state change around 2000, but that's not to say there wasn't one. Given that an exponential is by definition caused by a constant growth rate, and we don't have enough data to confidently declare that, I think it's a fairly difficult claim to support. To me, it looks as though around that time the signal (the rate of decline) began to rise above the noise, which could be a state change, or it could simply be that the noise has remained reasonably constant while the signal asserts it's rule over the decline.
