Here's an incomplete list of graphical RSS readers for Linux that have had releases in the last year:

QuiteRSS [http://quiterss.org/]

KDE Kontact [https://userbase.kde.org/Kontact]

Liferea [http://lzone.de/liferea/]

RSS Guard [https://github.com/martinrotter/rssguard]

Seamonkey [http://www.seamonkey-project.org/]

Thunderbird [https://www.mozilla.org/en-US/thunderbird/]

Firefox ("live bookmarks") [https://www.mozilla.org/en-US/firefox/products/]

In the console, I like newsbeuter [http://www.newsbeuter.org/]

That's a great list and some options I haven't seen before I'll try out.

I use monboob (http://weboob.org/applications/monboob) on my little VPS to fetch rss feeds and send them to me by email. This way I don't need an extra application, and it is automatically synchronized on all my devices, thanks to yet another decade-old standard: IMAP

(I do need to set some filters on my Gmail so they don't appear in the INBOX, though)

There's Feedreader, at least:

https://jangernert.github.io/FeedReader/

I'm sure there must be others out there for Linux? There are several available for OS X (er, macOS); I use a commercial one called Reeder, but there's also NetNewsWire and the open source ViennaRSS (which appears to still be in active development).

A couple more tips:

1. offrss 2. Bamboo reader as an extension for Thunderbird
