I agree on the mix, but I think our approach means a lot of self-selection into the TOD community.  There's very few people who have the ability to A) consume and produce research, B) see the forest AND the trees.  We lovingly call those people "geeks."

Finding "geeks" who can actually communicate and use A and B in their communication.  Well, there you have it.  That's TOD.

People will come here for the ideas and the research, but they might go elsewhere to spread that knowledge.  I am ok with that.  We can't do everything, but we can continue to do things that matter well.

That's why I haven't been averse to going down the ethanol path for a while.  It's an important and related debate.  There will be many other debates that come and go inside this much larger one.  

I guess my point is this: we need all types here, but most of all we need people who give a crap and can understand the scope of the problem, which is a really difficult thing to do.

What I haven't seen in the what is it good for thread is that TOD surely is a source that educates people. I 'm not sure how much of a scientist one needs to be to grasp certain things, and I don't believe that is the essence. People come here to find answers to problems. And there is no guarantee that they will more easily be found with a degree or experience in a field. You will have to remain open to the possibility that it is technology thet IS the problem, and not the solution. Which is sometimes hard to accept for those whop work in tech fields. Still, as Einstein said, you don't solve a problem with the same way of thinking that caused it. Energy may well be predisely what he meant.
