I remotely know that personality test, but I have never taken in myself. Anyhow, I totally share that "at appropriate times" aspect. I prefer SMS over calling. I'm active at facebook, but I always have the chat option disabled. And with some of my friends I exchange pen-and-paper letters, I like the slow-paced personal touch there is with real mail. But, yes, all of this comes with the aspect that both the sender and the receiver maintain the freedom to decide when they feel like reading & replying.
