Hi, I just wanted to let you know that Blogtrottr, the RSS to email service, now uses PubSubHubub to subscribe to feeds.
The push model is a real benefit to us, as it allows us to deliver updates to our users far quicker than we could achieve with polite polling, and helps alleviate a great deal of server load. We have a blog post on the matter, and would love to be listed on your companies wiki page. http://blog.blogtrottr.com/2010/10/ah-push-it.html Regards, Sam Bryan Blogtrottr
