So you're suggesting there shouldn't be any (for example) instant messaging in the web browser, it should be in a separate application.

Well, it's pretty clear what you mean now, and I guess we'll just have to agree to differ. Real-time AJAX applications in the web browser are the future, and I know I'm not the only one who thinks so.

Also, if you think I'm trying to say the back button should do anything to an IM conversation, you're misunderstanding the whole issue.
