Sorry, but even with the graphs, I'm not seeing how 1000 users continuously connected for an hour doesn't translate into a lot more server load that 1000 users

  It requires negligible (no?) traffic to keep a TCP socket 'continuously connected' when data is not being sent. (The only resource cost is the state at both endpoints remembering the socket exists.) OTOH, every 'poll' involves a lot of socket and HTTP request/response overhead traffic -- even if there's no update necessary. Still, this article overclaims the comet case. Polling is often easier to understand/implement/debug. It requires less server-side state and may be less likely to hit practical server-side implementation limits.
