I'm a casual user, and accustomed to pages that don't dynamically expand themselves. I figure I'm at the bottom of a page, but then it force-feeds me. I'll say now that DuckDuckGo uses the same algorithm, but gives the user an opt-out. Youse need an opt-out at the top of each Flow-enabled page.
Where page content exceeds page size, it is better to permit the use of refills as used by most search engines, or chapters as used by How Stuff Works.
With Flow, the major turn-off is the ever-decreasing size of the scroll-button, coupled with the absence of the Light At The End Of The Tunnel.
