IMO, "electronic communication" text, email, im whatever leaves out a lot of the "nonverbal" cues that come with normal human interaction, you don't even convey tone like when on a phone call, much less all of the physical cues that are there in person. The flip side is it would seem to make it easier for a person that is socially shy to do something outside of their "comfort zone" because they don't have to actually talk to, or look at the other person.
How old is this person? I have a young coworker whom I don't know if he has ever actually talked to his gf, I would guess they text each other while sitting across the table at dinner
for someone like that it's prob cool, someone who still uses a phone/in person at their primary way of communication prob wouldn't like it
