I'm actually rather having fun with the idea. I've started with the characters-based-on-Twitter-avatars idea, and I'm curious to see how long it will take the people who I've hijacked into the story to realize they've been appropriated as a character model, in a sense. As I've said before, I do know some of them, but not all. Sometimes, as is the case with the Shift Commander character, I just really dug the profile picture.
And now, I am rambling. I may do another update tonight, as I'm still writing from the previous one. Time will tell.
Thanks for riding along!
