I tried to follow the advice. It's clearly someone who is working with computers and for a long time. The comments are touching various topics (from tech to society to random stuff) and it's likely that the person is behind a keyboard, not on a mobile phone: comments are rather long on average. That's quite compatible with sysadmin psychological profile.
