I've been working on my Careers profile, and stopped by the homepage. One of the things that I immediately noticed is the "featured jobs" section. Although I had just finished entering a list of US states where I would be willing to relocate, only one of the six jobs listed was in one of those states.
Seems like an easy win to me. I know I'm not willing to move to California under almost any circumstance, so showing me those positions is pretty much useless.
