They noted that repetition of the basic information, beyond a certain point, was counter-productive. So it is with the Peak Oil story. The facts, in neither case, change, but the amount of new information while accumulating (vide the superb work that Leanan has done with Drumbeat over the years) is often repetitive or confirmatory of earlier stories and thus harder to turn into interesting and exciting new material. There are developing stories that justify continued interest in the topic, but the slow pace with which some of the stories unfold make it difficult to sustain interest.
I would agree with this assessment. He ends:
And with that off my chest I will return to writing about the evolving problems. My hope at the founding of TOD was that it would chronicle the events through the Peak, it got to nearly the Peak, though I don’t anticipate that this will be a pleasant story beyond that point. But, that coverage will now shift to being only at a new location at a time chosen by the TOD editors.
