The experts say effective networking begins with examining your existing network, so I thought I would see what InMaps, LinkedIn’s visualization tool, could reveal about my professional network. As you can see below, InMaps shows each of my connections as dots with lines showing how they are connected, colors denoting groups, and the dot’s size increasing with the number of cross-links within my network.
I was struck by how many of my connections are from my AAAS Fellowship in 2010 (blue); while these are valued contacts, it does prompt me to network outside of that group to expand my reach. You might note that my network is relatively small, (< 200 contacts), and that is because I find that can't keep up with a set much larger than this (probably related to Dunbar’s number, somehow).
LinkedIn has also developed Swarm, an animated word-cloud visualization of the most actively searched job titles and company names.
P.S. Thanks to Alex for the tip!
