And that's wrong. camelCase is when the first letter is lowercase, and all the rest are upper.
So his "ClassNamesShouldBeCamelCased" should've been "classNamesShouldBeCamelCase".
THAT is proper camelCase. What he displayed is a variation of camelCase.
Which just further proves my point. There is no single one proper notation. It's dependant entirely on what the people using it agree on and can read properly.
Personally, camelCase isn't my preference. Hungarian Notation is by far my favourite notation, and it's the one I use if I'm going to be doing any serious programming. If I'm just throwing something together for myself, I use whatever I happen to use. Furthermore, the only class name that didn't use his variation of camelCase was my main class, which means that he was nitpicking at a mere 1/6th of my class names for a reason that doesn't exist.
