Nofollow generally used in forums, blogs and other messages, the representative of these links is not the webmaster can control, this link is not a vote of confidence.
And Zac, such as SEO experts said nofollow used in some internal links to achieve control of the internal link weight and the flow and distribution of PR purposes, the most common is the use of the site at the bottom of the contact us, privacy policy, User terms, website ads and other links. These links above the content is not very important, to the PR programmed not much use, and these links are often the whole station on every page, if not using nofollow, the whole station link weight will be equal flow to these pages. And like privacy policy these pages generally users are rarely shut down, want to bring traffic through the search rankings, is very very few. So the weight flow to these pages is wasted.
For example, a home page has 30 links, contact us, privacy policy, user terms accounted for 3. That is to say, the home page link voting power has 10% wasted on these pages, though important but unlikely to have search value. Similar links put on the nofollow, you can actively control the link weight and PR in the site distribution.
