Somebody should do that again. It is amazing when you think about the fact that that’s a Facebook started. I thought that was a pretty good movie by the way.
There was a website called “Hot or Not”, where users would rate submitted pics, and the average rating displayed

One thing that dating sites could do (but which they would NEVER do) would be to give users feedback on their own desirability. Users go through the profiles of potential matches, swiping left or right to indicate “might date” vs “not interested”.
The site could give people feedback on their percentile ranking on “might date”, but would never do so, because women who did not score high would quit in outrage.
