it is following the one-page design form your lynda course.
the commenting out of .entry-content also did not work. I am still hunting it down but I think it is a bug within one of the media rules.
The issue is in the style.css of the stock simone theme because when I turn it off in firebug it goes away.
Ok figured out –it is in the sidebar.
I commented out
/*.entry-content,*/
.entry-footer,
.tag-links,
.post-navigation,
.comments-area,
.paging-navigation,
.author-index { margin-right: 0; }
in line 104 of content-sidebar.css
