thoughts on comet?
comet programming is essentially a way to provide a more "live" feel to the website by updating instantly. One example of whether this is useful: Let's say I am answering a question and someone else answers the same question, I would get a update informing me of the answer before I press enter or do a refresh. So if I am posting a similar answer, I could stop. Such a style is shown to keep users more engaged. Refer to <http://quora.com> for such a website
