Though sometimes I refer to Graham as PG when commenting on Hacker News, I consciously try not to because I&#x27;ve not met him and I try to separate the feeling of intimacy that stems from having constructed a virtual Paul Graham from the actual person I have not met. Within the context of Y Combinator it probably makes a lot of sense, but on Hacker News, it draws a bit of a circle around insiders and outsiders. I don&#x27;t think it&#x27;s intentional, but I don&#x27;t think it&#x27;s particularly constructive either.<p>Not knowing what &quot;PG&quot; means can be taken at face value. People can still write amazing comments and submit great news items without knowing or caring who &quot;PG&quot; signifies.<p>I think you make a fair point. Hacker News is constantly growing and Paul Graham has been less active for many months and since Sam Altman became the public face of Y Combinator, Graham has been less visible and the ability to recognize all the Ycombinator partners by Hacker News user name isn&#x27;t particularly valuable.
