Dan: the original reason for wanting to understand who the meeting participants are (as a subset of all IETF participants) was a desire to track our participation. Similarly to how we already track where they come from, and present that pie chart in the plenary. You raise an issue about making deductions about the leadership bias based on these numbers. I agree that such deductions would be highly questionable. But enabling such comparisons was not the intent. It truly was merely to understand where we are in terms of participation, and how it evolves over time. Jari
