@larry5729 "...However, at times it is difficult to know who to believe."
It’s not too dissimilar from an employment interview where you are interviewing your initial candidates, separating the talkers from those with proven experience.
People with hands-on experience can usually explain in detail what they’ve reviewed, completed, and failed at, backing up their findings and conclusions.
Outside of that the rest of it is parroted noise, inexperience, and limited value-add.
