If you were deriding some executives it'd be another thing. But I'd steer clear of mocking the little guy on your corporate blog.
I know it isn't your intention but your somewhat mocking commentary at some of those candidates may be taken in a bad way and reek elitist - neither qualities you really want to project as a founder, imo.
Example: Computer illiteracy wasn't one of the job requirements.
A kinder way to state this would be "We really need someone who is proficient with the computer."
