Google real time indexing

Have you heard of PubSubHubub? Well you'll soon feel the effects of it in your searches and your rankings. It is a new realtime publishing protocol that Google is working on to index the web. This is a major game changer. Eh? I hear you say... basically content publishing is going real time. Do you use sidewiki? Well it's now available in Webmaster tools. If you use it I'd love to know why & how.
