Re: window.setInterval()

I sort of question the 30 seconds part of this too. I assume you're
using ajax to find out if there are updates, yes? You could also hold
the connection open on the server-side for a period of time and have the
client just reissue the request when the server returns. Take a look at
the way facebook does chat, or yahoo finance does price updates. The
browser makes a request and the server holds that connection for a
period of time, returning as soon as there's a response, or after a
timeout so the client knows things are still good.
