Yes, Lee, interested to see how the 'serial premium' business model works too. The young adult market is a good one for this sort of thing testing. Although I'll warn you that the Internet is largely an advertising based revenue stream unless it's software or and educational product. You might need to publish the full through Smashswords or Kindle and use the serial concept to hook people. Let these sites do the marketing and the formating for the various readers out there.
