One of my favorite apps on linux is FeedReader. Long ago when I used Google products they had a great RSS reader built in, but they phased it out and got rid of it. If you are a fan of reading blogs but dont want all of the emails for new articles piling into your inbox, FeedReader is a very nice app to organize and handle off of your RSS news.
Lets just get right to it and install which is very easy with a PPA in the terminal. Cut and paste each line into a terminal and press enter...
sudo apt-add-repository ppa:eviltwin1/feedreader-stable
sudo apt-get update && sudo apt-get install feedreader
The only caveat is this is not a true RSS manager but more of an RSS client. You will need to create an external account on one of the RSS web services (usually free) like InoReader, Feedly, or Tiny Tiny RSS. The beauty of this is that your blog feeds will all by synced up.
FeedReader has some nice features such as sharing an article to your Pocket, Instapaper or Readability accounts, as well as desktop notifications of new articles, keyboard shortcuts, and tagging of articles. As seen in my FeedReader image above, we list our subscribed blogs in one area on the left side, however if you have a lot of blogs you read you can make and group them into categories. Linux blogs, home improvement blogs, science blogs, whatever your desires.
Another bonus is you can even add YouTube pages to your feed! Example of a feed would be to go to their YouTube page and click onto the pages "Videos" feed and thats what you would plug into FeedReader. Heres an example of a YouTube link...
