I just checked with Mr. Google and Wickipedia for RSS. It is a method of importing articles into a Forum such as this.
Not sure where you got this, but that's not correct. RSS is a way to get content from a site, regardless of what it is. You can then use an RSS reader to view content from all of the websites you frequent. That way, you could go to one website, and see your news, any new blog posts from your favorite blogs, and any new posts to this forum.
However, I don't believe RSS handles "conversation-style" content well. You'd basically just be getting all the new posts in random orders, rather than in threads of conversation. Not terribly useful for forums.
