Sorry I was unclear. I use the Newsticker feature of Emacs to read feeds ( https://www.gnu.org/software/emacs/manual/html_node/newsticker/index.html ). I don't know enough to recommend standalone programs outside Emacs.
For the past few years I've been trying to live as much as possible in Emacs (i.e. use it as more than a text editor). I just got tired of learning new programs that work wildly differently every few years. For example for IRC I went through ircII->bitchX->irssi->weechat, all of which are very good but I just got tired of the churn. Similarly for pine/mutt/alpine. Emacs has always been there, all the parts of it work somewhat similar to each other, it's very well documented. And I suspect it will stick around for another few decades anyway.
