Not really sure what this does or how exactly I will find it useful just yet, but none the less it is interesting to look at.
The skinny on what this is can all be summed up with an excerpt from this Mashable.com article LinkedIn Launches Tool to Visualize Your Business Network by Ben Parr:
LinkedIn has launched InMaps, an experimental project that creates a stunning visualization of the connections within your business network. InMaps sifts through all of your connections, detects the relationships between them, and groups them into different network clusters.
It color-codes and clumps networks together so you can see the depth of your connections in one interface. InMaps is an insight into who the major connections, bridges and influencers are in your network. People with bigger dots and their names in larger fonts have more connections (and typically more sway) in specific clusters.
Here is what my own network looks like…enjoy!
