People who post "informational" or "educational" on-line videos who know VERY little about the subject they're attempting to demonstrate. For example, I watched a video this morning of a model car kit unboxing where the host identified a vintage Chevy Rochester Fuel Injection unit as a "turbocharger" and the headlight buckets as "Baby Moon Hubcaps". I have also seen WAY TOO MANY automotive "how to" videos presented by self proclaimed "mechanics" that, in all actuality, don't possess the skills to properly air up a bicycle tire. Maybe the old adage "it is better to be thought of as a fool..." should be revised to "it is better to remain an unknown fool than to post ignorant, ill informed on-line videos and remove all doubt."
