Well, I love CJ's writing, and I'm surprised LTMP hasn't been published somewhere, it's that good. I think Circumnavigation could be that good, too. But I sense that CJ has a a certain...reticence in advancing this story very much in each chapter, and part of that could be chapter length - there's only so much you can write in each chapter when the postings happen every week - along with all the research and backstory that has to be developed along the way. It's a lot of work, it has to be.
And I think there's a certain amount of poking at people in the forum about cliffhangers. So some are deliberate to develop tension, as CJ says above - and some of it is sheer glee at being able to keep the joke running.
I mean, there's a meme on reddit.com about Gabe Newell, the founder of Valve, who makes the game Half Life. Half Life 3 is in production and has been for years. Gabe Newell is a heavy guy. Anytime anyone mentions Gabe's weight on reddit, someone responds with "well, there's another month added to the release date". And Gabe has been known to chime in, all in fun, and agree that yep, that one added TWO months. Or whatever.
All this aside, the only criticism I have about Circumnavigation is its pace. It doesn't seem that the story advances very much when you read it as posted every week. So the solution I've arrived at is to only read it once a month and catch up. I just did that, so now I'll stay away for a month and come back at the end of February and catch up again.
It's a great story, I don't care how many chapters it has. Thanks for writing it!
