I think of this as the social media Gell-Mann Amnesia Effect. You see comments from folks with zero insight and no doubt no specialized knowledge of the relevant industry, recognize that they are likely just making an off-the-cuff comment without any value, open the next thread where it's less obvious how little industry knowledge the posters have, and resume giving their comments the benefit of the doubt.

I fall victim to it with some frequency. Almost any comments here about the medical industry, of which I'm a veteran, are just wildly ignorant - and spoken with the same strident confidence as comments about the airline industry (for example), about which commenters are likely just as profoundly ignorant. But then I don't know they're profoundly ignorant, and suddenly I think, gosh, that person has some incisive insights.
