xeuledoc is a tool (hacking?) that can determine the owner of a google doc and often the name and email are available. I’ve been testing it and it seems to work well! Although it seems to only work with publicly shared documents.
The interesting thing is that you may not want your name and email address available to every one! Ever shared info via a google doc? You may be exposing at least your name and email to people who are unscrupulous – might be time to think about all the docs you may have shared! Is it a good thing that your email address and name are linked to this data?
It also seems to work with the “Security setting” anyone who has this link. It will be interesting to see if google “fix” this, and how long it might take.
Note this above example is included in the application as published by its owner.
