Facebook

While exploring Facebook it was very easy to find people's profile even if they weren't a Facebook "friend" of mine.  It was easy to see what they have been posting as well as information containing where they live and work.  Many people I ran across had several hundred friends, so there are many opportunities for those people to share what they post.  People need to keep in mind whatever they post others can share and then their friends have the ability to view and share.  It is extremely important that people think about what they post before posting.
