I think something isn't explained so well. In the Ales Yeast goes to the top of the fermentor not in the end of the process. It's just the opposite. It's on the top during the active fermentation, and when fermentation slows down, yeast gradually becomes less active due to the presence of alcohol and lack of sugars, and bit by bit settles on the bottom of the fermenter.
Nice idea though, to get people informed about the beer.
