Agile Developers Needed

I wish those companies who advertise themselves as being agile would actually act accordingly.
Granted that there are true agile shops, in my experience the standard case is that those who pretend to do agile just do a "Scrum for the Project Manager" and that's it.
So the open question is, do the "open positions" from that study include all or just truly agile companies?
I know there is a side topic in my question, "what's true agile?", but that's not the point here. I just feel like agile has become a buzzword in every job description. Also, I get shivers when I see "Business Analyst" in the list.

If demand outstrips supply by 4 times then salaries for "agile developers" would be going through the roof, but they're not.

There are so many things wrong with this "study" (as described in this article) that it's hard to know where to start.

Simply counting job postings without verifying that a real opening exists is one problem. How many of these postings are duplicates? Also, many job postings are for phantom jobs -- jobs where the hiring manager has already identified who he or she wants to hire but the position still must be posted.

How did they count available candidates? It doesn't say. And what makes someone a candidate for an agile position instead of a non-agile position.

Why would salary go up if productivity of typical new hire is 1/8th or less than productivity of a seasoned developer?

I think what they mean is that demand for IT engineers outstrips supply. The Agile part has become just a buzzword.
When you hire somebody you look for skills and experience, the agile part is a nice have since anybody can learn that in no time when joining to a team.
