Friends
If it is public, are you happy that everyone on Facebook can potentially see everything you write?
I don't mind, and I would feel neutral.
If it is Friends of Friends, what are the implications of posting to a relatively large group of people that you may not know?
Nothing much, unless the matter is rather sensitive, then things may go quite chaotic.
Who can look you up and can search engines link to your Timeline? Who could potentially see your Timeline if this is set to On?
Everyone
How many apps are listed as having access to some or all of your data? How many do you remember authorising?
126, 126
Do you trust all of those applications to use your data responsibly? Why?
Yes, I am not a celebrity or someone famous, I doubt they would even care who I am.
If one of these applications were bought by another company, would you consider removing the app from Facebook? Why?
No, I am lazy to remove them and also, I doubt they would really care who am I.
