The same is true for some of the more vocal accounts here on HN, as elsewhere. I don't keep a list of usernames but a few folks talk with authority across a range of topics - both tech and adjacent interests - and when they happen to step into some niche where they obviously don't have the same depth, and yet project the same level of authority while being not entirely correct, it really does recalibrate that "believability index".
