Well, my ideas of what's useful have been continually disparaged since I started this article (see above, includig the post in which someone dared to compare me to a...sociologist!), so perhaps I don't have a clue about this issue. I see your point, but I still don't see how saying reinforcement is the effect of reinforcers is informative. Well, a positve approach is sometimes the best, so I'll see if I can come up with a proposal for a new opening.
