If the quote doesn't automatically give you a back-link, it can still be a pain to get more context. If it does, then that's probably passable but it still might be a few hops to get back to the start of a discussion and you don't get it all on one page (in a traditional flat system) if there is much activity at all. Twitter may be able to do better with a loose grouping in of related tweets (which should include all tweets being replied to) while still preserving some semblance of a flat system, but I don't know if they do - I don't use twitter extensively. I do know that I've found it sometimes difficult to figure out what is in response to what in the little I have used it, though, so I am skeptical.
