Yeah, there's a lot of whitespace - I'm not the biggest fan of all that padding on the blog / archive dates template, or the L-R padding on the home page, but I hear "more space" is all the rage :)

Mostly I noticed the difference in the Docs. The elements are called out more explicitly and it's easier to find things on the docs, which have considerably less whitespace: https://docs.djangoproject.com/en/1.7/intro/tutorial01/

Yes, even I thought the same. I hate that the home page has a lot of content that I have to scroll down to view (at 1440x900 resolution).
