I've decided the web site LinkedIn is really useful for networking. I recently posted a recommendation my co-worker wrote about me and now I've asking recruiters left and right to connect with me. Some are accepting!
This web site is a little weird too. There is a fluctuating list of people that LinkedIn suggest I connect with -- some of these people I haven't spoken with in ages! And maybe I don't want to talk with any of them again! At least for a while longer!
Overall though I think this site is worthwhile for networking and if I get a GIS job through in a warm and beautiful place, perhaps let's say Los Angeles, even better.
