I went to bed tonight with 99 followers and woke up to find 101! I've reached my goal. I tweeted the book coupons.
Now we shall see if I can reach my goal of a completed manuscript by June 7. I think I might make it, but parts of it will still be a mess, and probably not ready for readers. (I realized that one of the thing that was slowing me down was trying to edit and shuffle material before it was all there - now I'm not worrying whether a scene is in the wrong place. Just get it all in there.)
