It's fitting that we should hear about technology affecting dating from the guy who wrote the book behind the movie He's Just Not That Into You, Greg Behrendt.
Greg's feelings about tech (who's pictured here on the left in his cameo role in the movie) are more about how it can enhance relationships — but shouldn't dictate behavior:
I think that in your life you have standards for what you will or will not tolerate, what works for you. If you’re comfortable having an entire relationship on text, that’s up to you, but you basically teach people how to treat you. If you want a phone call, ask for a phone call, and accept nothing less.
To see what else Greg said, just
You want to see somebody in person? Let them know. The great thing is, it’s expanded the way we communicate so it can be part of [it] — you know, sometimes when I’m doing something like this and I can check in and shoot my wife an email or a text and say ‘Hey, I love you, just letting you know. Busy, can’t really call right now.’ But if I did that all the time, it would be problematic.
