Yes! You can see my profile here:
http://pinterest.com/misstarren/As you can see I effectively created some really diverse boards that I feel represent my style and taste. It's all about being well rounded and... Well, awesome.
So it's not necessarily for just pinning your own items. As a matter of fact, I think it's not looked upon very highly to do so. You can look up your items that have been pinned, too. I typed my name into search and found tons of my stuff.
I also find wanelo.com to be very successful. I believe it depends on the product and demographic...
