I think Tinder nailed the concept that many people don't want/have time to write 10,000 words about themselves or answer stupid quizzes. At least in my experience, a lengthy profile isn't going to help you; it can only hurt, and the item of largest importance (as the article states) is the pictures.

Tinder seems ideal to quickly move from 'swipe', to a couple text messages, to a date. It's the first date that really matters. I'd argue that most people will know within the first 10 minutes of the date if they have any interest in continuing. Messaging back and forth prior to this date doesn't seem to do much except waste time.
