I was throwing a concept around with a friend of mine about 2 years ago where the dating site would learn what type of people you're attracted too when you click on profile pictures (using some kind of facial recognition technology presumably) and then be able to suggest profiles you would be potentially interested in. The side effect of this would be that shy people could still keep photo's in private galleries, but still get taken into the overall equation and potentially matched up with someone who might find them attractive. Fortunately (or unfortunately? Depends how you look at it I guess) we had no real interest in starting up a dating site at the end of the day.
