Would it be worth while having a weekly tutorial challenge? Possibly bi-weekly, monthly…
Each challenge could have a specific techneque to demonstrate, e.g. vertex parenting, uv texturing, IK, Hair Guides, Fluid Simulation, etc. and the over all theme of the tutorial would be left up to the submitter. As long as the tutorial clearly demonstrates the technique somewhere within it would acceptable.
The format of the tutorials could also be targeted toward the blender wiki. In this way we could flesh out the thinner parts of the documentation.
Just a suggestion - comments, ideas?
