Thanks for your comments. I agree--HN has been quite disappointing lately. For a place that's supposed to be full of tech contrarians, it does sound like an answering machine around here sometimes :)

Regarding your retort, I believe it should possible to measure the economic return of every social benefit. I strongly suspect that there are social benefits that more than pay for their own cost.

However, the most effective way to prove this is by measuring it.
