Amazing data about how Americans now meet their spouses, and whether there is any difference in happiness outcomes.  Study paid for by eHarmony, but published in the Proceedings of the National Academy of the Sciences.

"From this table we can see that eHarmony had the very highest satisfaction scores. Interestingly, “blind date” was the second lowest satisfaction score, and that’s how I met my wife."

I don't know. All these results look pretty similar to me, actually.
