Actually, I like that the messages are only the message and none of the thread, it saves on resource usage. I have a threading email client (the GMail web interface), I only archive emails so I always have the context locally. I like how the forum works and how fast it is. My only gripe is that emails are sent immediately, and then when a poster edits their post that sends another email. I'd prefer some delay, so posting only sends an email after 30s or so, and if you start editing the post it delays it for 5 minutes or until you save + 30s.
