Exactly. Although, I've become particularly careful about things like posting about my husband or in-laws. My husband and I have a mutual friend who will report back to him about my posts, and I'm facebook friends with four of my in-laws. Better to write those things in my diary instead.
Oh, absolutely. One should always be careful what to post, like was said in this topic before: if you wouldn't say it out loud where anyone could hear, then don't post it in your status.
I would never post anything that wouldn't be okay for the whole world, but especially my husband and family, to know.
Edited because this new keyboard is causing me typos.
