Although there's above intermediate/pro information, mostly these are the basics. There are some points like "the brush tool", which if you have THE program you discover it anyway. There could've been a separation between "very basic" and "advanced" info.
Useful if you've only got one of these programs, and don't really know where to start. Also useful if you have some knowledge about this and that, but not cohesive enough yet, or crave to know more. For example the info on PHP was a welcome surprise for me, and some AS/graphics goodies too.
Overally, it can give you some ideas about what and how, and also has a familiarizing potential.
To the makers: Gratz! You've succeeded in covering a whole lot of things, and presented it in great style, smooth and nice. What I missed, were more pictures, as they could've reduced the amount of "read it" text, for example in "drawing trees".
Thank you all for the effort it took to make it. Peace
