The problem with people putting information online is that people are stupid and don’t understand what they’re doing or how to do it properly.
As an information professional, a librarian, and a citizen of the Internet; this Google search scares me. What is it? Well, if you typed it out, this is what you would type:
filetype:rtf | filetype:ppt | filetype:pptx | filetype:csv | filetype:xls | filetype:xlsx | filetype:docx | filetype:doc | filetype:pdf “this document is confidential” site:gov
And in essence what it’s doing is searching governmental sites for any and all document types with the word “This document is confidential” in it.
So much for confidentiality.
