Say I have a page that has a continually-refreshed status on it. The idea for the service is that it's something you can keep an eye on in the background while it continually refreshes itself. How do you effectively communicate that it will refresh every so often?
Currently, I just display something like "status: X as of Y seconds ago; refreshes every Z seconds." It works, but it seems that some people do not read the "refreshes every Z seconds" part and complain that they must manually refresh the page.
 Some clarity on the "progress bar" in the mockup: it's more of a meter. Think of it like a CPU monitor or similar -- it's not always increasing, and it's not representing "time to next refresh" or anything.
Also, I know some people are against auto-refreshing, but this is a case where it is a necessary and desirable feature, so ideally discussion should focus on how to present the information and not why it should not be done.
