When Fallout 3 was released along with it's GECK, Bethesda created half a dozen YouTube video tutorials to teach us the basics and some advanced topics on how to use the GECK to create content. They were very well received and taught alot of us how to use the GECK - they were invaluable.
I would ask now that New Vegas is released; if Bethesda and/or Obsidian would be willing to do some additional tutorials of this kind?
My selfish modder instincts are to ask for tutorials on advanced topics that we struggled with; such as LOD and LipSync. However it might be more fair to ask for tutorials on the new features specifically added with New Vegas; such as the new Dialogue Editor, the new Weapon Mods system and the Crafting interface (if one exists, I can't find it!). Such tutorials would be right in-line with promoting the features of the new game, and would help the community out.
Thank you for reading and considering,
