I used to think Tinder and the like put too much weighting on looks, but Aziz Ansari in his book asks how that is any different to approaching someone in person? You wouldn't approach someone you didn't find attractive, and you can't get to know someone before you've approached them.

Additionally, I would argue that you can tell quite a lot about someone provided they've made an effort with their profile. You tend to know music taste, career, where they're from, and interests.
