Now that I understand the problem and solution, I will share it in more detail with the community for anyone else that may come accross the same problem.
The issue was that after creating a new site on an author instance, when viewing it on the publish site the page was not rendering correclty. The visible symptom was that initial HTML tags (for HTML, HEAD, META, and BODY) were being generated, but the content was not be filled in.
I did Activate my content properly, however, because it was a new site, and I had generated new components and site templates which resided in the "apps" folder and assets in the "etc" folder, they were not available to be rendered and so the HTML page was blank (because they could not be found on the publish instance). What I did was use the "Activate Tree" under the Tools section to publish content in /content/mysite. What I missed was using the Activate Tree to publish items I had created in /etc/designs/mysite and /apps/mysite.
