Pinterest would be a great tool for a dating website. It shows places I want to visit, my favorite foods, my style, favorite music and things I love to geek out to! It's all about me! If you don't agree with my pins then we probably aren't a good match :P
It's also great because it will usually take you to the source of each photo. So if you see a hair tutorial you like you can click the pic and it'll link you to it's original website. All the above photos can be found on my Pinterest and most have the source attached. Do you have a Pinterest account? Recommend any I should follow?
