I actually use Outlook as an RSS reader. It's not very good but it works and that way everything is in one place.

Also, I think Outlook is much better than any other mail/calendar client I've ever used.

I read HN, Reuters, Re/Code, Atlantic and New Yorker in Outlook. I love the mostly text-only experience and am finding that I read content in a less prejudiced way when all the color distraction is gone.
