While I like that there are a lot more posts per page than otherplaces, it would be nice to have crumbs at the bottom of the page instead of having to go all the way back up top to move up a level.
I see links to forum of the topic and higher levels at the bottom left of the page. There is also a quick navigation (NE arrow at bottom right). Furthermore if you click the blue up arrow at bottom left it instantly takes you to the top of the page.
