Just wanted to add value to your great information on no follow topic.
NO Follow tags are useful:
Though NO follow tags might not transfer Link Juice to your Page, but we cannot forget that we will be surely benefited with respect to Crawling.
When that page will be crawled definitely on that page we have our link present too..so it will be crawled as well.
This feature of "No follow" helps a lot in SEO.
