But I have come across something he has written which (arguably) is written BB (Before Blogging).
In Systematic Theology Vol 1 The Triune God Oxford: OUP, 1997, p. 39, he writes:
"In one way, a reader is therefore more free - it may seem, indeed, omnipotent - over against a text than is a listener over against a speaker. A speaker is there to defend his or her intention against my interpretation. Once discourse has become text, it lacks this defense."
That was in 1997. In 2018 a blogger can post a text and can choose to defend it in the comments section. Or not!
