That's not how public figures work. Influential public figures are influential largely because they are credible. Credibility requires history. Anonymity precludes history.

Take Jeff for example. Jeff has a history. Jeff is a credible game developer with an impressive development history. He's a known factor in the creative community. He's got credibility out the wazoo. As such, we give his words extra weight because of that. In an alternate universe where this article was written by internet-man-of-mystery Bleff Blogel, we probably wouldn't be having this discussion, because he would have no history to back up his points. It just wouldn't have the same impact.
