Interesting idea. A few questions...
What would be in the mag which would not be on the Simply sites? By that I mean, would we need to buy the mag if we already come here?
Will it have content that was not released on the Simply sites? That would seem like a waste of your own efforts, to limit which tuts go where...
Personally I come here for LW knowledge. To some extent I resent buying mags which have a load of content I don't want to read - so the maya tutorials would be a turn-off for me. The Photoshop stuff might sometimes be useful, I know that package well, but someone always has a new angle on something and its good to see those
What is the goal of the mag? It might be a great way to raise the profile of the sites - if people see the mag in shops and then visit the sites.
