Online dating websites and apps have, in the last two decades, become quite popular. We all probably know several serious couples, some even married, who have met online. However, some people argue that online dating is superficial, unfulfilling, and isolating. For one, many apps such as Tinder are designed so that you swipe "yes" or "no" on a person after seeing their picture. Although many people put up biographies, you have to sort of go out of your way to read the biography, and many people decide from the picture alone. I have also heard the complaint that younger people use dating sites and apps to hook up, which isolates people who want more serious relationships and discourages them from dating. Finally, people also argue that these apps and websites have created a generation of people who don't know how to date "normally," and instead rely on online dating.
I personally can understand some of the criticisms that I've heard, but I also think that online dating can be beneficial for a lot of people and groups, one example being LGBT people. I know it can be hard for LGBT people to date, particularly because most people are heterosexual, and also because you can't tell if someone is LGBT just by looking at them. With online dating, you can connect to other LGBT people who prefer your gender.
I do think that online dating is fairly superficial, but "real" dating is pretty superficial in many ways as well--mutual attraction is necessary for a relationship. I do think it is harder to get a sense for someone's personality online, which can lead to bad dates and frustration. In all, however, I think online dating is something that works for some people and not for others, and it is not going away any time soon.
