Exactly. The people who post these types of things love to feel like a 'real designer' and they feel that being a real designer is laughing at uneducated clients and pleading the end of Comic Sans life.

But in reality.. if everyone was just as educated as you on the subject, you would most likely be out of a job. That's the problem with guys that post things like this. They try design and make things pretty, but they should be designing for and educating the very people they make fun off. That's there job, to create a design or website that persuades or educates the consumer and makes sure the consumer takes the call to action.

It's not the consumers job to know ANYTHING regarding the web or design. It's our job as web professionals to make it easy on them and fulfill the desired action.
