I am on LinkedIn, and the job section was useful for pointing me in the direction of a few agencies and job adverts, but all were ultimately fruitless. I keep my profile up-to-date only as I think it's something I think one should do in this day an age, but as yet, I'm struggling to find a use for it. That said - i assume it's one of those things that the more you use it and put the networking effort in, the more you get out! Oh and one more thing - about automated e-mails from job boards rather than agencies: I am a Product Design Engineer; I have a degree in Industrial Design and a Masters in Design Engineering, and work as a Product Designer. I am not therefore interested in the barrage of adverts and opportunities for Graphic Designers, Electrical Engineers, System Design, or Railway Engineering!!
