Yesterday RSSRadio's servers were upgraded to support PubSubHubBub, this new technology allows providers to push content rather than the servers having to poll for new shows.

What this means is that rather than the servers having to look for new shows at regular intervals, providers will notify either the Google Public Hub or the Superfeedr Public Hub and RSSRadio's servers will send out a push notification to get your show downloading immediately.

This technology is currently supported by over 10,000 podcast feeds.
