(Coming a bit late to the party but) As Bob said... When Facebook is involved, there is no privacy. Period. The end. Do not pass go, do not collect $200. The entire business model of Facebook is built around selling people's information, private or otherwise. Do not post anything there that you wouldn't want potentially shared with the entire world. Also make sure to look into how much information you're giving up every time you "like" something.
If a Facebook friend's comments appear in my news feed and I respond to it, do my comments automatically get sent out to all my other Facebook friends? I know they can control what they receive. However, I want to make sure at least certain people don't see my comments I make on another friend's comments. Basically, I want some control of the audience. I have broken down friends into groups and changed settings so not everyone sees friends comments on my wall. I just don't know if my comments on a news feed will show up to all my friends. I've been very confused about this - finding it difficult to get my question answered. Please help. Thank you
