What's the incentive for my friends to do all this work for me for free? Why would I bother setting up a profile for a friend? It seems like a lot of work for no benefit.
The OkCupid profiles make more sense: you make them so that you look good and you get dates. Work -> reward.
Because they're your friend and you want them to meet someone that's right for them...? I have a friend whose roommate made an OkCupid profile for her because she wanted her to meet more people.
Actually there are plenty of people who would do something like that for their friends. I don't know much about the dating scene but I have a number of friends who do dedicate time and money to arrange dates for their friends. I'd say the benefit you get is the satisfaction you gain from helping out a friend.
As someone who is recently married, my incentive is for them to get hitched and hopefully knocked-up so my wife and I aren't awkwardly the only married/baby-ed people in our friends' circle!
