Somini Sengupta of The New York Times looks at what you need to do to protect your privacy on Facebook now that their new search tool has been released. Some tips involve installing particular apps, but the most important one appears to be spending an evening with your profile and disassociating yourself with anything and everything you don't want to be linked to.
Go to "activity log." Here you can review all your posts, pictures, "likes" and status updates. If you are concerned about who can see what, look at the original privacy setting of the original post.
In my case, I had been tagged eating a bowl of ricotta with my fingers at midnight near Arezzo. My friend who posted the picture enabled it to be seen by anyone, which means that it would show up in a stranger's search for, I don't know, people who eat ricotta with their fingers at midnight. I am tagged in other photos that are visible only to friends of the person who posted them.
The point is, you want to look carefully at what the original settings are for those photos and "likes," and decide whether you would like to be associated with them.
"I don't get this Facebook thing either," said one woman whose friend request I had accepted in January 2008. "But everyone in our generation seems to be on it."
If you are concerned about things that might embarrass or endanger you on Facebook -- Syrians who endorse the opposition may not want to be discovered by government apparatchiks -- comb through your timeline and get rid of them. The only way to ensure that a post or photo is not discovered is to "unlike" or "delete" it.
Make yourself a pot of tea. This may take a while. The nostalgia may just be amusing.
