Google has rolled out an experimental interface (and some real-time tracking features) for its Feedburner service. This is really the first upgrade since the service was acquired back in 2007.
The new interface according to Google provides real time stats for clicks, views, and podcast downloads. Feed publishers are now able to see what content is driving traffic from feed readers, micro-blogging services like Twitter and other syndication sources in real-time.
Those publishers using the FeedBurner Socialize service are also now able to receive stats on how much traffic feed items are receiving, as well as from feed reading platforms like Google Reader directly.
Google did note that subscriber and reach numbers will still be calculated based on a whole day's worth of requests (based on the traffic received for the prior days) but item statistics now reflect the traffic feed publishers are receiving in the moment. That's right - Feedburner has real time stats.
