A few days ago I discovered a new service called iFeedReaders. It´s currently in beta, but it works really good. It´s a lot like Feedburner, but you don´t have to subscribe to anything, you don´t have to give out your information other than the url to your site. iFeedReaders will take care of it for you.
The objective of this site is simple, create a one central place to send your feed and have all the subscription services coded and ready to go.
