Often on multiple apps at once, users can swipe through dozens of profiles every minute and plan multiple dates, whether in hopes of a love match or a hook-up.
When we first studied online dating habits in 2005, most Americans had little exposure to online dating or to the people who used it, and they tended to view it as a subpar way of meeting people.
Striking up a romance through a dating site or app is a well-established method of meeting people in 2016.
It's also increasingly risky when it comes to rape.
Rapes related to online dating increased by nearly a factor of six -- from 33 in 2009 to 184 in 2014 -- according to a report released Monday by the UK's National Crime Agency.
That's a small fraction of the number of online encounters, to be sure.
