From the viewpoint of a HN lurker: -pg - Because he's PG -edw517, mechanical_fish - Due to frequent sighting of their comments -tokenadult - You'll always find him in threads that contain discussions about human intelligence/alternative education -potatolicious - U.S. immigration discussions + Canada vs. USA issues -markbao - Entrepreneur, 16 years old -mahmud - A technology nomad (originally from the Washington DC Metro, now in Australia) These are the ones I can recall from top of my head. I do recognize many other usernames, of course. Also, I would like to point out I have no inclination to upvote the individuals mentioned above. I think it's more about frequency, since most of them tend to partake in discussions that cover a wide range of topics. Just because they're experts in one area doesn't mean I'll find their opinions insightful no matter what. Each posting/comment is taken into consideration.
