Ever view source in GMail before?

I had always been curious about why GMail seems to be more responsive than most of the other web applications I had use. Out of curiousity, I look at the html/Javascript source code that was generated and rendered by my browser. I was unable to understand what was actually being generated as it seems to use a single function named D() to render its display. Thus I made a search on Google and found out about the Gmail engine and protocol. I think if this new technique takes on successfully, others may follow suit and this will change the way web developers work dramatically. Read more about it.
