A Frames version of a webpage actually has "sections" on the webpage. When you click on a link in one section, that link usually pops up in another section, while still keeping the original section (where you clicked on the link) intact. I don't see that happening on this site, so it might be for David's future use.
I don't use WebTV, so somebody else has to answer that question. It must be better somehow for people that use WebTV and not a computer. Maybe it's formatted for a tv screen?
