To me, this does not sound like the same thing as Newest Nodes.

Newest Nodes is a list of nodes that were posted, in all sections, since the last time you hit the 'I've Checked All These' button. Newest Nodes is great, but it doesn't really help you find nodes that were posted before you hit that button.

gaggio's suggestion is to have the section headings on the Monastery Gates be links to the respective sections. In other words, you could scroll down to "New Obfuscated Code", decide 'Hey, I like these, I want to see more!' and then click on the section heading to go to the Obfuscated Code page, rather than scrolling all the way back up to the top of the Monastery Gates page to find the link to Obfuscation.

I think it's a pretty good idea, and would make the interface to the site a little more intuitive.
