Thanks for responding @scipio! I fundamentally think you a creating a really good thing here... and look forward to seeing it develop. I'm glad you're including different metrics to reflect participation.

I remember well the days of "Google watching" to try to figure out how to get our web sites to figure more prominently. And I understand that it's challenge. Metaphorically speaking, we all KNOW that "Sony Corporation" has authority in electronics, but what about the smaller guy who's every bit as expert but doesn't have a $100 million budget? Ranking for "value" will of course always be somewhat subjective...
