Excerpt from this article:
When Chris Rackliffe, a motivational speaker in New York, met a potential friend at a bar last weekend, it never occurred to him to exchange phone numbers. Instead, the two swapped Instagram handles, and have been liking each other’s posts. Rackliffe said they’ll probably meet up in person again soon.
“It’s so much more casual to give someone your Instagram handle and keep in touch through stories and DMs,” Rackliffe said. “Swapping numbers feels so serious and stiff nowadays.”
