So it's definitely still manageable. And the story is, thus far, proceeding along nicely. I'm not quite as far along as I figured I would be (for the number of words written). I guess that I have plenty of plot. At this rate, the book will chalk in around the 80K-90K range which, for humorous fiction, is a comfortable length.
(If you're curious, I've put up a small excerpt from the draft. I chose the bit where I basically intro/explain/justify part of the novel's premise. You can find it here or, in fancy Flash form, here.)
Edit: Using the word meter tool that altivo, who's a good 6K ahead of me (cheers!) , used in his LJ.
