Where the vetting mechanism fails, the system fails. This has happened in countless instances from the current financial crisis to nearly every product, market, environmental calamity, or political failure in recorded history – the referees who were supposed to keep their eye on the ball, did not. Likewise, where a vetting mechanism is effective, the system is efficient.

EBay does little more than defend the vetting mechanism (feedback system) and entrepreneurs do the rest. The credit score allows companies and people to capitalize and securitize assets. The US legal system keeps the game of commerce as fair as practical. Police officers and school boards keep our society safe and smart. We often overlook the importance of vetting in our communities.

Today, we find severe problems in finance and government and people are investing their knowledge assets in social media as the place to “store and exchange” their present and future productivity – instead of debt. As such, social vetting is taking many different forms to validate, qualify, and quantify those assets.

While the progression may not be noticeable, there will be a tipping point where the medium has built enough trust that it can support a currency. This new currency needs to be only a little bit more “trustworthy” than the currency it will replace. This is the point where knowledge becomes tangible.
