Spec says include a link to self, so lets do that.
Hub discovery
Refer to resource feed
Follow/Unfollow pubsub subscriptions
Subscription in callback
Validate callback intent
Set callback intents against subscribing user
Discover hubs in atom feeds
Ok, pubsub should be in rss only...
Discover feed self
Discover hubs in feed
Doc update
Boot pubsub
Validating and debug
Validating and debug
Handle alternate naming
Backwards compatibility with 0.3 hubs
Parsing arguments
Aaaaactually, it might save a bit of time if we do publish the hub in the main header. It's probably safe to do so...
