Joseph, as someone who doesn't follow every discussion in this thread, I am curious as to how you are defining "productive"?
Yes, it requires some synthetic variable, of which there are a few in the quant literature. (For example, Priedhorsky et al. defined a damaged article view (DAV).) However, it could be something as simple as what Spinellis and Louridas (2008) imply: a reversion is evidence of an unproductive contribution (ignoring revert wars for the moment), and so what percentage of all edits to WP are reverts? Has this changed over time.
