I actually figured out a great (for my industry) interlinking scheme which actually ensures that just about every page links to a fixed percentage of other pages.
I rolled it out onto some new pages only - just 5 brand news URLs with major content on a 400 page site.
Then - just my luck - my homepage vanished from the index the next day! I'm not linking the two events, but I'm not going to make ANY more changes whatsoever until that darn homepage returns.
