Hi Ian, always good to get some actor-network theory;-)
Thinking a wee bit more about this and about your subsequent comment, I am convinced that different writing techniques have effects on the way we learn/think. For me blogging is a lot about getting my own thoughts straight. The ease of editing & rearranging makes it easier for me to rearrange my my thoughts. I suspect that different technologies have different effects too. Writing on a phone or tablet or a particular application helps or hinders in different ways. A blog post can for me, start as an idea on my phone, sync to my iPad for padding (sic) out and on occasions finish up on my laptop.
As you say, lots to unpick.
