Key Takeaways:

Social media is an unreliable source for critical information, often filled with misinformation and unverified answers, even for high-stakes topics like medical advice or aviation.
Relying on incorrect information or flawed procedures, such as misinterpreting RNAV approach glidepath interception, can lead to operational problems and safety risks.
It is crucial to prioritize expert-verified information and documented procedures over social media popularity, as demonstrated by the author's personal research to clarify undocumented aviation nuances.

Where do you get your information? Do you go to experts, or rely on what people tell you in a Facebook post?

I try not to spend too much time interacting on social media because to me it’s largely a waste of time. It can also be a huge source of wildly speculative, uninformed answers to questions that people pose. Often the correct answer to a question is in the comments, but how does one sort it from the other 95 comments that are incorrect?
