With the tech job market right now, most tech workers can find jobs that pay the bills easily, so they'll tend to raise their level of discrimination a little. So they look for the one that pays a little more, is working with some neat technology, and basically works with their schedule (Or whichever other list of nice-to-haves).

When you can afford to be picky, "high quality" takes on a different meaning.

I think the point the parent was trying to make is that responding to a recruiter isn't likely to get you ANY job, because they don't understand the job reqs they're recruiting for nor the people they're trying to place.
