Expand on this thought a bit. It seems like what you are saying is that the trick to speeding up the page load time is for the client to put everything in a SQL database and then just dynamically keep changing it, right?

What are the arguments for and against this?

What about the web sockets idea you're talking about? That would also speed things up? So I imagine it would not speed up the initial page load, right? It would only speed up the capture of new replies and posts, right?
