This thread is worth reading if you are a Google docs user.
Short version: When you export a document from Google Docs, Google replaces all your hyperlinks with links that allows Google to monitor the interactions of everyone you share your document with.
This hidden link replacement can potentially be used to build a model of your professional relations, where people who interact more with your content are considered a stronger relation.
Think about the implications.

Today I found out that google docs infects html exports with spyware, no scripts, but links in your document are replaced with invisible google tracking redirects. I was using their software because a friend wanted me to work with him on a google doc, he is a pretty big fan of their software, but we were both somehow absolutely shocked that they would go that far.
