Unless I'm missing something, just give your phone number and text.

While that never died, social media is the modern rolodex. And on top of that, someone can jog their memory of you and warm the iron back up a little bit.

Swapping social media details has been more effective for me because often I don't pounce on a number immediately. And I would hate to lose contact with someone just because I didn't.

Social media keeps someone on the fringe of your vision. Bit easier to spark something from that than cold-texting "hey, it's Jeremy from that one party two months ago. remember me?"

Besides, at age 30 and having been dating for a long time, I can't tell you how many times social media has given me serendipities like someone asking what to do while visiting the city I live in and I can PM them with "hey, I'll show you around."

I rather meet prospective dates in person not via tinder /coffee meets bagel type appsm I understand that you are exposed to far more people online, dating pool wise, but in University I was surrounded by 50,000 students and I thrived by physically going to organized clubs and events I was genuinely interested in and chatting it up and exchanging info. Now outside of University, these apps and even online dating get more locked in when you are exposed to less people on the regular.

Some women find it odd if you don't have a FB. This may have changed slightly in recent years though, as trends away from F have started.
