I too, sometime see posts in this thread and then they vanish... I'm guessing (hoping) authors deleting own posts.
Regardless, using websockets is not something doable in foreseeable future. We had that discussion (what to use? plain HTML/AJAX/websockets?) back when the development started and settled on plain old HTML with some AJAX here and there. That was probably not the best decision, but it's not something we can easily change now.
I was indeed talking about Web Sockets, but then I remembered that the whole game uses mostly static pages, so I decided to remove my post. I mean, it's still better than AJAX, but the difference isn't big enough, IMO, to justify rewriting their server (and it would be a good idea to redo the whole loading and browsing flow as well).
