Examples of Web Sites Using AJAX or Push Technology on Their Home Page (or other useful pages)

Question

I'm looking for a list of links to any examples of well-designed sites you might know that use AJAX and possibly HTTP Streaming to push data to the page or make updates to content of existing HTML elements.

Ideal examples would be sites that update somewhat frequently (every 10-90 seconds) rather than very frequently (every 1-5 seconds) nor just occasionally (beyond 90 seconds). Subject matter is not important as long as it's clean. I just want to demonstrate the concept using well-executed examples.

Samples might include: * Counters, such as live visitor or goal/progress trackers * Timers/Countdowns that might reset periodically * Data updates such as live headlines, posts, blog comments or others * Any other AJAX/COMET examples you have seen that are really well done

I do like Digg's Labs demos, but they are all Flash. I would like only non-flash examples though.

Thanks!
