A letter to Pleiades users about privacy

Google's privacy policy changes and a keynote talk by Mozilla's Stormy Peters at PyCon last week have prompted me to write a letter to Pleiades participants about the state of privacy in this project and possible impacts on their personal privacy. Dear participants: please read it. Pleiades has it fairly easy because the acts of searching for and contributing to information about places in antiquity are generally smiled upon in Western societies that trace their intellectual and cultural roots back to the Greeks and Romans, but that doesn't excuse us from having a stated privacy policy and disclaimer. We'd be pleased if this letter inspired other projects to do the same kind of analysis and discussion.
