Funny, peakers weren't playing with averages back in 2008 !
Peakers aren't really peakers anymore, are they? When peak turned out to not be a peak, but a plateau, suddenly they were plateauers. If the recent data is to be believed, perhaps they will become peakers again except at a new level, somewhere off in our future yet. So they pulled the fire alarm a little early...what's the big deal? Have you noticed how few of them are left? In a few years we'll have another peak (or plateau) and their children can recycle all of these wonderful scenarios, and guys like you can point out how those ideas didn't work over these past 7 years, and an entirely new peak oil boomlet will happen all over again.
Let us not forget that Hubbert wasn't the first calling for peak oil in the US, and when he did, he predicted it would happen mostly likely before 1950. Why? Because all the easy oil had been found. So even he had to keep up the clamor for a couple of decades before he could become the prophet of peak.
The reference, in case you are interested, comes from his Technologist days, back in 1938. Which was some 2 decades AFTER others were calling for a US peak in oil production. Those who don't study history are doomed to repeat it, and this particular concept fits that pattern pretty well.
