Let me know if this is old news.

I didn't really get my point across in the Huddle.

A couple of my clients and lots of sites I see go so deep that PR is dropping 3-4 notches in some cases.

What I was getting at in the huddle wasn't a site map that a visitor could follow rather than an invisible graphic link(s) off of a websites Index to a "Noindex, follow" links page that would link directly to deeper parts of these web sites. In doing so, passing much more PR around and into the deeper parts of the site.

Yes it would be a blank graphic and possible require but from what I can tell graphic links pass PR just as well as text links.
