The new look for blenderartists.org forum, etc. is what I’d call it corporate/professional. I think that this look works for the direction that Blender is heading in development wise and community wise. Blender is a more polished 3d software. Blender is definitely not the same opensource 3d software it was three years ago. Blender artist are getting more capable at using Blender to handle all of their work. Blender artist own professionalism and progress can be seen more today that ever with each new render. This new look can also stand up against other 3d community website designs and give Blender artist their special place in the greater 3d universe.
Good work on the part everyone involved in the new design for blenderartists.org!
