I would be curios to see a LinkedIn graph showing (and proactively finding) evidence of this whole saga.
That is, I would expect to see less movement of employees with certain talents, between conspiring companies.
Is there a way to get this information off of LinkedIn?
I am guessing it would be possible to pull it out of Google+ profile pages, but I am not sure it has historical data, or been around long enough for that matter.
Facebook would surely have it but I doubt this information is accessible.
