Am I a Poor Communicator or a Texting Genius?

Face to face, phone and even email communication may be dead. Case in point, this text conversation I had yesterday with our babysitter:

Me: I know it’s late notice but any chance you could babysit tonight (tues)?

Babysitter: Yes i can babysit. What time do you need me??

Me: awesome. let me check what time [my wife] will be home and get back to you in a few

Babysitter: Okay.

Me: can u b at our house around 5:50 tonight? will probably be back around or just before 10pm. is that ok?

Babysitter: Yes. Thats fine.

Me: thank you!!

Babysitter: No problem!!!

This entire conversation took place over about 5 minutes. I never talked face to face with our babysitter. Never picked up the phone. Never sent an email. And yet she showed up at my front door at exactly 5:50 pm.

Is it wrong that I made babysitter arrangements using only text messages? Or am I brilliant for using the preferred communication method of teenagers? You decide.
