Linkedin Changes not as effective for recruiters?

As I've mentioned before and discussed on other blogs, Linkedin has pushed back on high volume users that use the system to gain new access to potential candidates that you previously didn't know.  I actually had my account locked and had to fight to get it back.  Because of that battle, I have also dropped my premium status (and fees) and started using other social networking sites. 

Shally Steckerl has some good comments and suggestions at Recent Linkedin Changes: Boom or Bust?  Some of his suggestions will get you the needed new contacts but it does add a new step (email) or two.
