Well all three of the things he put in the first post are important.
Time: The longer the better because people want value for money

Techniques used would great to be explain why they need to be done not just explaining how to do them and maybe what other areas they could be used in.

Finally each tutorial should focus on a particular aspect.
eg: modeling, animation, dynamic ect
so the audience doesn't get confuse at learning too much at once.

U may disagree but everyone probably has a different way of learning and trying to find a happy medium maybe hard.

although im sure your tutorials will be great

BTW my first post was really just me ranting on(sorry) didn't meen to annoy anyone (just joking). i just wanted to come at this from a different direction. Instead of saying what i want in a tutorial i wanted to say what not to do in a tutorial that may be wasteful. VIDEO tutorials are way better because you actually see how its model and ur not just reading through something and guessing half of it.

Oh and whos Birch?(again joking)
Theres some great talent on this site.
