I don't really pay attention to what section the posts are in. Since I come here at least once everyday. I use the "new posts" function on the menu bar. That brings up everything I haven't seen since my last visit. This way I don't miss anything in any of the sections. I use firefox, so I just go down the list of posts, right click have that post open in a new tab, once I have opened all the posts I want to read, I just go through the tabs reading and commenting as I feel the need. Once I have closed all the tabs, then I know I have gone through everything I wanted to read or comment on.

Hope my method helps others in their navigation.
