NOT PINTERESTED

I know a lot of you are into Pinterest and while I have an account myself, after about 3 times of trying to add images to my albums I was bored. I honestly just don't get it so please explain it to me. Is it basically a scrapbook of stolen images of things you like/want (just what we all need, more consumerism)? Or is it just inspirational and something to cure boredom? I saw stationery on there I liked but of course since it was Pinterest there wasn't any way of knowing where the hell the stationery was from! What is the point of that!? And it's not very creative...just ask any artist their opinion of Pinterest. But clearly people are loving it, but people love Facebook too and I really don't get that either.
