I am a publisher who uses Feedburner and I love how it burns blog feeds directly from blog installer without loosing subscriber base. When customers subscribe to my new feedburner address the service starts tracking subscriptions which apparently is known as burning feed. I use Channel feeds for channels as I run a small operation compared to large publishing houses that make use of megafeeds for the entire network. I find Feedburners blog listing to be slow in syncing to the rest of the account and feed foundry is sluggish. Feedburner provides good Customer support and is easy to use. I like the look and feel of the RSS page and get good stats on my feeds.
