I like the idea, though, since there are so many different styles for characters and so many different things for sets, this probably wouldn't work out as well as one would hope. It would probably be better to create a good set of tutorials from armature building to dressing to prop building and painting. The reason for this is that when we make films, we want them to be original. After all, if you were making (example) Coraline, you wouldn't want to use the same armatures as those used in Wallace and Gromit, right? Nor would you want the same set pieces, but chances are, you would want to take ideas and alter them some. Say you have a good lamppost tutorial. You can use it, but still alter the final product so that you can call it your own (so it fits the style of your film: horror, suspense, comedy, etc.).
I would fully support creating tutorials for various, often overlooked, aspects of the trade.
