Timeline is dumb, unless you're someone who posts tons of pictures and comments. I have 11 pictures on FB, so my timeline wouldn't be worth much. Shooting Star, the purpose of it, supposedly is to give a visual of your "life." But, it's only your life as you've posted on FB. My son has it, but it hasn't changed the way he posts.
I have no interest in Pinterest. I just don't spend that much time on the computer, except for TE. If I need to research, I do, but it's pretty easy to do that on your own.
