The HN leaderboard shows 100 users with > 15500 points, they mostly all seem to be active users, and the scores seem to be doing the usual long tail dropoff that such distributions tend to do.
So I would expect there to be a ton of active HN users with more than 1000 points.
according to a comment in this thread, there are 5500 users with over 1000 points. Whether they are active or not is unknown. Whether they want to view pending comments or just read and comment like normal users is unknown.
If you are in this >1000 karma club, please approve this comment. I have been a user for 1044 days.
