I use the Fluid HD setting on a 17" MBP, with safari full width. Recently, with lots of relatively short articles (and collapsing older articles down), I am seeing the right sidebar on the main page running under the footer at the bottom of the page. Not sure what the best fix is. Making the footer clear the sidebar will leave a huge chunk of whitespace. Making the footer smaller to fit beside the sidebar might work, but would still look odd when the sidebar runs extra long (or rather, content runs short).
