Privacy Settings - Facebook

I was already pretty aware of the safety/privacy settings on Facebook, which is the only social media account I use.  Occasionally I will modify the privacy settings of posts to either make them posted only to me (for future reference items) or just friends.  Facebook tends to use the previous one that was used.  I had actually posted something just to myself early last week and then couldn't figure out why people weren't responding to my posts later in the week until I remembered making something private.  I did actually notice though that people could search my name and link to my Facebook account so I changed that particular one.
