I wonder if we could change from an impression to some data? For example: (A) How many people* are subscribed to ietf@ ? (B) How many people are eligible under the current NomCom rule? (C) How many people are "active" in some other sense (e.g. have sent mail to *any* IETF list in the past year)? How many people are in (A) only, in (A) & (B), in (A) & (C), in (B) or (C) but not (A)? We coud add (D) How many people are subscribed to ietf-announce@ * people = distinct email addresses excluding the + construct. These data exist if someone in the Secretariat could extract them.
