Converting RSS feed to Atom via Feedburner for existing blog

I have an RSS based blog that I now want to convert to Atom. Feedburner can change the output format in one click. Will my existing subscribers notice any change on the reader side? (other than taking advantage of the ex开发者_运维百科tra atom functionality)

Feedburner can adapt dynamically to whatever a user needs. This is taken from their site:

SmartFeed: Reach the widest possible audience while publishing a single feed on your blog or site. Translates your feed on-the-fly into a format (RSS or Atom) compatible with your visitors' feed reader application.

Just enable that and you should be good to go :)

I changed the output to Atom, posted a test blog post and checked my own feedreader. No difference on the reader side so I'll assume this is standard behaviour.
