That could be deliberate, though. People may deliberately want more boundaries from anonymous means of communications. They post on Reddit instead of Twitter when they don't want folks to know who they are; they tweet instead of text when they don't want to address any particular person; they text instead of call when they want to downplay awkward pauses in the conversation or hide that they're multitasking; they call instead of videochat when they don't want the other party to see their facial expressions.

The customer validation results you got could be explained by a prestige hierarchy in social interactions. In general, addressing people directly and hiding as little of yourself as possible signals higher status, because it implies that you are less ashamed of who you are. Nobody's going to say "Yeah, I'm a hermit who spends all my time trolling people anonymously on Reddit", they'll say "Yes, of course I want higher quality face-to-face interactions." But when it comes to their moment-to-moment decisions, very often they would rather troll people on Reddit.
