Never Distribute Word Documents

Companies should never, ever distribute Word documents beyond their firewall. When they do, bad things happen. As you may know, Word stores a massive amount of hidden meta-information about the document, including changed made to the document. As such, competitors and customers with very little acumen can discover data that you might not want exposed. Here's an example. This guy wrote some code to search through Microsoft's site, locate any accessable Word documents, and download them. Then he analyzed these files and discovered some data that Microsoft probably didn't want distributed.
