I like my text properly formatted and with pretty much every CMS editor out there I always have some confusion when it comes to titles. The post or page has a title and then sections inside it also have titles and they are second level titles. On most CMS you have the option of titles or headers starting at level 1 through 6 (that maps to h1, h2, through h6 in HTML).
For example, this is Confluence, a tool that I really like:
The confusion that I get here is whether a subsection to this page should have Heading 1 or Heading 2. Sometimes Heading 1 will be displayed with the same font, size, etc as the title of the page, so, by using Heading 1 you are almost creating two pages in one. But in other CMS, Heading 1 is the top level section heading and the title of the page is a special title that will always sit above it.
The new WordPress.com editor does this correctly by being very clear that your first option for section headers, after setting the title of the page or post, is h2:
I think that was a very neat solution to the problem. Bravo WordPress.
