1) I've found that supplementing material makes a massive difference in sales. However, when you see a larger percentage of the revenue, you definitely feel more inclined to create supplementing material

2) wewut isn't tied to fast moving software at all. I wouldn't consider that a necessity, though it does help ensure future editions
