When the simple word processors came in, writing became crisper, less dense - just because of the way we could instantly edit on the screen. Now the ability to mash up words and pictures and links and songs and tweets is what matters. I can't imagine what writing will be like in 2154.
Any time you write history, you insert your opinion. You pick and choose what you are going to write about. I feel really happy not inserting myself. I spend too much of my life inserting myself. It's just great to let other people carry the narrative.

I write about how in Midland, the mayor instituted water conservation measures like restrictions on car washing.
