Responding to Tom's RFP
Tom Carroll has a great list of things he's looking for in a feed management service. Let's see how FeedBurner stacks up!
"The migration to the service must be seamless for my current subscribers"
Answer: Yes ... see "Can I keep my original feed URL but still use FeedBurner?" and "Pointing an existing feed URL at your new FeedBurner URL".
"The service should provide a suite of metrics that allow me better understand who, how often, when, how long, how many times (You know what I mean, the numbers)."
Answer: That's the foundation of FeedBurner. I think you'll be pleased with the stats available to you.
"In the case that I choose to leave your service, I must be able to migrate my feeds transparently and also be able to migrate my usage data."
Answer: To leave, see "Ciao, FeedBurner". To export your usage data, see "Awareness API and Subscriber Numbers".
"I would like support for one click subscription to the various news readers."
Answer: See our Browser Friendly service. To see it in action, click on my feed in a browser.
"The service must have tight wordpress integration."
Answer: Please see Steve Smith's excellent WordPress FeedBurner Plugin.
"Integration with analytical packages say like Google analytics"
Answer: We don't have an integration with Google analytics, but how about Mint? And wait until you see what we have cooked up after we ingest Blogbeat!
"feeds must be human readable"
Answer: Again, see our Browser Friendly service.
"I would like it to support leave comment from the feed."
Answer: Use our "Add a comment" FeedFlare ... it's somewhere on this list of "101 FeedFlares for a Better Tomorrow".
"Configurable support for social network services like Digg or del.icio.us (Sometimes I want it on, sometimes off)"
Answer: FeedFlare to the rescue. You choose which services you'd like to add to your items in your feed.
"Support for the widest set of RSS extensions"
Answer: Yep. We support them. And all feed formats.
"A strong record of availability, reliability and scalability"
Answer: This is the most important quality of whatever you choose for feed management, and it's our number one priority. I think our availability track record shows that. We also have a number of contingency plans in place that we hope we never have to enact, like our "Feed Insurance" capability that all of our publishers get for free.
"Should support multiple feeds per site, no limit."
Answer: We support multiple feeds per site, no limit.
"Integration to see where my feed is bookmarked and subscribed"
Answer: Part of of our stats package includes the ability to see where the items in your feed have been read and possibly resyndicated. See "And There Was Much Rejoicing: New FeedBurner Statistics" for more info.
"Advertising, I prefer none."
Answer: No advertising, unless you want it and have a certain threshold of subscribers. See "Does FeedBurner put ads in my feed without my consent?"
I hope that gives you enough confidence to give FeedBurner a try, Tom!
