Quote - Not sure I really understand RSS... does this mean you can load just the thread and not all the other stuff (like ads and header) around it, like on an iPhone or something?

In this case I'd expect a feed (if one were to be created) to list just the topic titles for those threads with new posts with a link to the thread (Rendo could of course intersperse banner-like ads etc. as is done by some feedreader sites).
