Most of the tutorials were from closed beta testers - if only because the tools were down a lot this past week. We figured it was our duty to help out the community since were given the opportunity to test for bugs during closed beta.
A small point on the crafting discussion: It isn't a 'crapshoot' with leveling your R&D fields now, either. With the season 2 update, they brought in a UI element that shows you how much points you will receive from creating any given item. Still, some truly excellent updates en route.
