Follow up on "Older Workers"

This is a follow up to the previous post.

The blog post was still warm when this was brought to my attention:

The job description itself by implication excludes older workers as most college graduates are in their twenties. What if I’m an older worker that’s changing careers? What if I like sales?

There is a not-so subtle implication that only young people should apply for this position, many people will see this and feel that “I’m not just out of college, I probably shouldn’t even apply”.

Based on the implied bias in this posting, how many talented people are they alienating?
