What exactly does Blender do?
Here are some additional links that might be of interest/help clarify things
Of course the wikipedia entry :) http://en.wikipedia.org/wiki/Blender_(software)
A comparison chart that shows how Blender stacks up versus its major commercial competition as far as major functionality
http://wiki.cgsociety.org/index.php/Comparison_of_3d_tools
And the Blender gallery which gives some idea of the still content that can be created with Blender
http://www.blender.org/features-gallery/gallery/images/
Does Commons accept Blender working/output files? If not, should we?
I think it might be of benefit if it doesn't either Blenders own format (which individuals would need to download Blender to view - a 4MB or so download...) or any of the common 3D scene formats (either web 3D such as VRML, or X3D - or Collada)
