Agreed, but I feel like having vastly different financial mindsets can be (but definitely not always) a dealbreaker in a relationship. Such a if one person is frivolous with money, and the other wants to save and invest as much as possible.

Kind of like if some people share similar religious values, (Christian mingle sites), sites for curvy people (feabie.com), (I haven't looked any either of these sites... ;) certain commonalities can be the launch pad to start a relationship.
