I have been wondering, just what is the community at-large? Lately I have been checking the people who show up on the birthday list, which I figure is about as random a list as we will get. Generally speaking, over 90% of them never post, so that brings our at-large number down to something under 15,000, rather than the frequently mentioned 150,000. Even among that 15,000, most have only a handful of post, although I am not really sure how many posts one can hold in their hand.
I would be very interested in knowing how many members actually have over 500 posts, or even 100 posts, and how many of them really consider themselves part of the FlyerTalk Community.
