I agree with all those in favor of the tutorials.
The more, the better.
Also, when Conitec releases the next update with the shader library, what I would like to see is a reference sheet documented somewhere giving me a breakdown of what the version is and what card(s) it does or does not work with.
It would suck to release a game that featured shaders available only to ATI users or only to geforce users and have to find out the hard way.
