Yes, Pinterest has a gray area (for whatever reason) about sharing links. There's no worry on Twitter when I share a link, so I'm not sure why some folks are up in arms over Pinterest, but that's okay. We use it at a mortgage company to help share home 'stuff' like designs, cool homes, free guides and random awesomeness. First time home buyers love to dream about their awesome future homes, so it's perfect for that. I say embrace the new (pretty) technology and have fun with it!
