I tend to agree with this. I'm genuinely on the lookout for a service to replace Feedburner.
Buffer is often called "just a cron job" and I can assure you much of the work is in scaling up "just a crob job" to hundreds of thousands of users (alongside all the other aspects of the product). So I know first hand that "building a replacement" is not the hard part of the task. I certainly want to trust that you guys can scale this up and be a reliable host of my feed.
Our current FeedBurner feed has over 600,000 subscribers (don't ask) most days of the week. We know the difficulties of hosting constantly-updating info that's requested once a minute by hundreds of thousands of users: http://feeds.feedburner.com/~fc/neosmart
