WALL STREET JOURNAL - Together, Wall Street expects Match and Bumble to generate ~$4B this year. Online dating provides more specific results from a wider net. Tinder has ~10M people paying to meet someone on the app. But pitfalls abound. People use dating apps because everyone else seems to be using them. A recent study by the Marriage Foundation found couples who met online were six times more likely to get divorced in the first three years of their marriage than those who met in college or through family or friends. Romantic love may need to adapt to technology rather than the other way around.
