@irime, this is a great, fun read, as always. I definitely have family members who live and die based on the meme news they receive on Facebook. It's funny, there are all of the tells you point out here, including a host of logical fallacies - but it always strikes me, for the craziest ones, that the big giveaway isn't just "wait, this is batshit crazy."

Having said that, I'm always worried that I am susceptible to, and heaven forfend, responsible for, a different type of misinformation - the good faith, but ultimately incorrect reporter.

That's part of the reason I'm so big on disclaimers for my mycology posts for example - I really try to thoroughly inform myself before I make any statement of fact - but at the end of the day I'm just a bozo on the internet without any specialized training beyond auto-didactic study. And as much I think there's value in solo learning, I also see how the internet enables a different kind of ignorance in that regard - possibly even a more insidious ignorance than Facebook news.
