Several readers have remarked favorably on my decision to post only three times a week rather than (as I did with my other novels on SOL) daily. But one told me tartly that if I was going to use that schedule, he (or she; the reader wasn't specific) would appreciate longer chapters; said the short ones, like Monday's Chapter 2, were "annoying.". Fair enough. I certainly want to hold reader interest as A.I. moves along. I can't oblige about chapter lengths; they're dictated by the pace of the story I'm telling. But I can post multiple chapters. Today, Chapter 3 is also fairly short, so today you get Chapter 4 as well.
