Even though I am sometimes consciously aware that I should be using terms for writing rather than terms for speaking in my online uh, conversations, I gravitate to the latter because that is how it seems to me.
I answer an opponent in a comment section by writing "You said that..." and I will use formulations about my own communication that can suggest only speech, not writing, such as "...and I say again..." My writing voice is very strongly based on my speech, and those who have not heard me live would find it both familiar and jarring to compare my writing to my talking. Most of my original audience were folks who knew only the latter. My current audience has only a dozen who have talked with me.
I am certain I am not unique in this - such things are not possible. But I think I am on the far side of whatever measuring rod might be fashioned for this, as it has been commented on often. I smile, laugh, and have an animated face - and also narrow my gaze or sharply look over my glasses, with a bite to my voice, more than others. It's pretty vaudevillian routine the Wymans have, and I even on the strong side of that.
I so wonder what other people think when they write, whether they just naturally say or have conversation. Standard internet language would suggest that we think of this as talking more than writing. Though such terms as posting and bulletin board would suggest the opposite.
