I've never liked talking on the phone for more than 5 or 10 minutes.
I'm not on Facebook, InstaGram, etc. - I communicate with family and friends via text and/or email 99% of the time.
If it's something really important, then I'll actually call and vice-versa, but my life is simple and uncomplicated, and I keep my communication that way as well.
NOTE: I tend to text messages of love and encouragement all the time, and I know the recipients appreciate it, because they say so, and usually reciprocate.
So, I guess (in my case) its no less "personal" than a phone call.
