Sinqua Walls

The good thing about Twitter is that there's not so much of a wall between you and your fan base. They can interact with you, and it makes them more endeared to you when you interact with them. It's really fun in that way.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
