Thanks for the interest! I don't have any solo play experience myself, but another person (retr0vert) mentioned the same thing in the comments on the release post, and I think they're brainstorming ways to do it.
My 2 cents: I think the amount of content would be a plus for solo play (lots of stuff to draw from), but information discovery is also a huge part of the gameplay loop and that would be harder since you're seeing all the GM material.
