This is one of those fix one break another (potentially).

In order to have inline text wrap around the sidebar, the "sidebar" needs to be contained in the content.  Heading tags are block level elements by default, which is why it pushed below the sidebar .  I went ahead and made them inline elements so they will wrap accordingly.

Off the top of my head I can't think of anything this would break down the road, but just be aware we went slightly against the grain here and there's potential we run into something else down the road by having content headings display inline.
