I don’t think that it can be characterized either way in general. In some ways it can be bad: I personally have a difficult time in construing meaning in conversation. That’s pretty common though, but self-awareness isn’t as much, so we get “internet aspergers” who just don’t get the proper tone without body language.

It can also be an effective cloak for times when meaning can be more clearly conveyed without physical baggage. I suppose it depends on context.
