Would anyone else be interested in inserting a private version of a tracking pixel into each of their e-mails, so that you'd get a list of IP addresses where the mail was viewed back?
It would be interesting to see where mail was read versus where it is simply passed in plain text. Crowd-sourcing anonymous data might also allow us to determine which IP addresses belong to the NSA's systems.
