makes me wonder if the person you went on a date with cherry-picked you due to your data. (anyone who would post on hacker news is obviously a good catch!)
"the odds are good, but the goods are odd" may apply here
I think the "only thing" that would make me cherry-pickable from their data is that I used an autoclicker to give everyone a 5 star... I have mixed feelings about doing that, but I got a couple (surprisingly nice) dates out of it that never went anywhere.
