I think the point of the post was that the author assumed all the adds were actually for the same position. The problem (if that was the case) being that C++ programmers/Flash programmers/HTML designers are not interchangeable.
Even so - in other hacker news post people complain that employers don't understand that programmers are more versatile than just "5 years of Java experience". I have never programmed Flash, but I am pretty sure I could pick it up within 2 days or so.
It actually seems cool that they made an ad saying "no experience required". When else do you get that? And it makes perfect sense. Why would a student taking on the challenge be able to learn to program what they need?
