I'm sure he knows the answers, he was testing the op. Why does everyone these days with limited knowledge on subjects do 'how to' videos. Once upon a time to offer the masses your expertise you kinda needed to somewhat be an expert yourself. All that's changed these days.
Actually I've wondered about this and came up with a theory that makes sense to me.
Give me your opinion.
The larger the group the higher the percentage of idiots it can support
The group has to be a fuctioning group.
Idiots in the Navy(Army,USMC,Air Force)........lots
Idiots in the Navy Seals(Dboys,ForceRecon,Air Commandos(I'm old))...not tolerated.
In a small Job Shop.....not many
In a large factory.......EVERYONE knows who they are. Yet they are tolerated.
In a library .......junk is thrown out usually.
Something as large as the web or get to YouTube.......WOW
And no time to throw it out......
In fact one of the best way to find the right answer to NOT to ask the question.
But state a falsehood about anything. The experts will give you references why you are an idiot.......but you got your answer.
What think you?
