As you point out, staying relevant and useful is an important topic for all organizations involved in peak oil awareness raising. Dmitri Orlov makes that same point in his talks:

"I think I prefer remaining just a tourist, because I have learned from experience – luckily, from other people's experience – that being a superpower collapse predictor is not a good career choice. I learned that by observing what happened to the people who successfully predicted the collapse of the USSR. Do you know who Andrei Amalrik is? See, my point exactly. He successfully predicted the collapse of the USSR [but you've never heard of him]."
Essential Dmitri Orlov

As you point out there is still valuable work to be done tracking oil (and other energy) on the way down and the Campfire series also extends TOD's relevance.

But will your readership soon be consumed by the needs of everyday living? Not entirely, of course, but perhaps mostly.

Andre's question of:

But will your readership soon be consumed by the needs of everyday living? Not entirely, of course, but perhaps mostly.

is given a whole different perspective if the wording is changed to:

But will your USEFUL WRITERSHIP soon be consumed by the needs of everyday living?

On the downslope of the energy curve there will be a strong desire for information on how to adapt successfully. But only a tiny percentage of those individuals who are adapting successfully are likely to be:
1. skilled presenters of information
2. with time to write their stories
3. and TOD members

Creating and living a different lifestyle is hard work that takes much time and emotional energy, likely leaving little desire to document it for sharing with others. Perhaps some TOD members could take on the task of reporting on the methods and ideas of those they notice transistioning well?
* Hopefully with some moderation on the reader comments to avoid excessive demoralizing tearing apart of the pioneer's ideas. Such treatment just reduces the pool of those willing to share later. An example that pops to mind is how much grief one Campfire writer got over mentioning the use of a bread machine...
