Try it for whatever interests you the most in life, in the world of Things. Cars, artwork. Best feature is quick save of most things you see on the internet so you have instant photofile.
My SOLE complaint, they do send you suggested pins you might like every day, but I often find something there that I DO like. I find it invaluable, and have only some thousand images on my "boards" so far. A really deep-end artist could spend days seeking and finding inspiration. And, no, i do not own stock, am not an employee or agent--just use it and LIKE it.
