BashfulBob:
Just a thought - maybe the numbers for the second part are not lower because people have stopped reading, but are higher for the first part because they have to re-read it to remind themselves of the story so far. At least, that's what I tell myself when a serial nosedives.
I don't believe that the "viewed" numbers work that way though.
As I understand it, if a particular Library member clicks on a posted work, that counts as one "view" (even if he/she clicks off right away after reading only the first paragraph), however the same member clicking on it again doesn't count as another "view."
Many people apparently decide that they don't want to invest the time and effort to read an entire serial after starting out with its first part, especially if they don't find its content immediately appealing. Also, they may resort to 'picking and choosing' which parts to read based on the validation data.
As for those readers who might give up if part one of a serial strikes them as slow-moving due to the background being supplied by the author, it should be possible in numerous cases to start out with some spanking action, then gradually fill in much of the background as the plot progresses.
That's also just a thought... --C.K.
