I believe rather than focusing on people in your friends circle, it would be a better idea to focus on friends of your friends. Say an app that listed the photo and short bio of all of your friend's friends. You could then express an interest in somebody you would like to date and the app would notify your mutual friend and that friend would make an introduction. Ofcourse there are certain issues with this approach too like the mutual friend being someone you 'kindof sortof' know, or a mutual friend who happens to be an ex of yours.
