<bikeshed>A single-word element name would me more consistent with
other HTML element names. <content> would be rather generic, so I
think <main> would be the better option.</bikeshed>

It would probably make sense to add
main { display: block; }
to the UA stylesheet.

If Hixie had added this element in the same batch as <section>,
<article> and <aside>, he would have made the parsing algorithm
similarly sensitive to this element. However, I'm inclined to advise
against changes to the parsing algorithm at this stage (you have none;
I am mainly writing this for Hixie), since it would move us further
from a stable state for the parsing algorithm and, if the <main>
element is used in a conforming way, it won't have a <p> element
preceding it anyway.
