There are a couple of use cases in which it would be handy for there to be an automatically generated RSS or ATOM feed for public directories on keybase.pub. For example, I intend to distribute software from my site and it would be helpful if there was an RSS feed that would be updated every time a file changed or the directory's contents changed.
It's better for you to create this RSS feed yourself and save it in your public folder, because then it will be signed by you instead of Keybase, and because not everyone would agree on the same format for the feed.
