small CSS-styling errors/suggestions

1.)

On the defaut frontpage nodes are not clearly (optically) seperated (see attached picture). I would suggest something like

.node /* Node wrapper */
  {
  padding: 0 0 30px 0;
  }

in the austin.css (line 342)

2.)

I think an clear a:hover on navigation-elements would improve the usability. I'm not quite clear, what Mark B. suggested in the design-specifications at http://cmsshowdown.com/. On www.drupalshowdown.com/ itself the hover-elements are used inconsistent. The slider on the frontpage uses hover-elements, but "normal" pages don't use hover-element on sub-sektions (e.g. http://www.drupalshowdown.com/about). I think some CSS like

  #sidebar-right .block li a:hover /* The hover item in a Drupal menu */
  {
    background-image: url(images/subnav_active.png);
    background-position: left;
    background-repeat: no-repeat;
  }

in the austin.css (line 688 ff) could be an improvement.

Sincere regards
