Hi!
We have been asked a lot of times about showing custom RSS fields (comment link and so on) in article page.
At the moment the standard article page does not contain those custom fields because we like to keep things simple.
At the same time the internals of Feedreader are REALLY REALLY advanced and theoretically you can display whatever custom RSS field in article page. By the way - you can even specify your own custom fields if you publish feed. And then make Feedreader display those custom fields the way you want.
