I realize there's a Friend Feed, where you can control the activity you see from your friends, but wasn't there once upon a time a feature where you could control what activity you showed them? I remember there being such a feature once, and I remember changing my settling so that no one could see any of my activity. Now I can't find a feature like that, and I have no idea if my activity is being shown or not. It's been bugging me for a while.

You can find the link here :)

Thank you so much! This is what I've been trying to find!

You're quite welcome, glad I could help :D
