Email's best attribute is that its universal. But that's also a problem: spam, semi-spam, corporate mail to the entire company etc. I find the existing UIs still manage quoting and threads very poorly. I'd like see improvements in this area. I think a thread markup language might be the answer. Take the exact display of threads away from the client and only mail intent.
