There are different types of recruiters. Some are those worthless spamlords, who pester candidates with irrelevant jobs and submit worthless candidates to hiring managers. But the good ones look for good matches and good candidates, and don't waste people's time with junk. One recruiter placed more people on my team, with a much higher hit-rate, than any other one I dealt with; when I was interested in changing positions, I let him know, and after a month in which he didn't bother me at all, he pointed me toward an opening that was a perfect fit for me. If you build up relationships with recruiters, you'll learn which are which, and how to ignore the Robert Halfs and Manpowers while still getting the benefit of the good ones.
