Question about Facebook privacy?

[Foley]

If everything is private (and you have to be careful... make sure everything is set to friends only), all posts that you make on your wall, and all posts he makes on his wall are private. Can't be viewed, no jobs are hacking your profile or using bots. Any time you post to another persons page though, their settings might be different from yours, it might not be private. Either way, it's smart not to post ANYTHING online you wouldn't want your employer, your school, anyone seeing. That is just being smart. You never know when something you post might come back to bite you in the butt.
