I've suggested to a number of people that if you could find people in LinkedIn that could help your job/contract search
(for research, for resume expediting, to check for existence of unadvertised jobs, or to try to get a job created/remoted for you because of a very special skill match),
then you could write a linked in introduction to said person, and I would happily forward it (I recommend you give me hints about points to highlight in recommending you for this specific position/company, either in the portion of the intro that is for me, or in a separate email). It is better if I know you, but if I only know you via a contact or two that will vouch for you, I will still consider it. These introductions do by and large reach their intended recipients. I spent all this time in 2002/2003 building up a big network, someone should benefit from it. So here is the nuts and bolts of that:
This last link tells generally how LinkedIn can be used to help in a job search. Most people can do everything they need to with the free LI service, by the way.
