I've saved The Old New Thing feed and have taken a look at it with my Kindle. It does include visitors' comments and it's perfect.
But when I took a look at the recipe, it used the link,
Code:
http://blogs.msdn.com/b/oldnewthing/rss.aspx
which is just for the main posts.
The site has another feed for comments
Code:
http://blogs.msdn.com/b/oldnewthing/rsscomments.aspx
But I don't see the latter link being included in the recipe.
I don't understand it.
