Now think about your pin boards. They never need tidying. If you see something you want to pin, you just put it on it's own little categorically correct board and there it stays. It never moves. It doesn't go out of place. It just waits in it's little spot for you to come back and try it out, or even delete it. Nice and orderly. Just how you want it. It's refreshing really.
I'm not saying I want my life to be like pinterest. (Though if it were, I'd be much skinnier--from doing super amazing at home circuits-- and better dressed in something I sewed from old clothes and I'd be eating tastier food on my DIY'd table.) It's just nice to know that amidst the constant picking and re-picking up of things I do actually have a space somewhere that is neat and tidy all the time...even if it is virtual.
