Indeed! I use the FeedBro plugin for Firefox, with feeds for my various webcomics, a couple of blogs, a couple of news sites (including HN), a Forum, a couple smaller subreddits, and more recently my favorite YouTubers since Google can't get it together when it comes to notifications of new uploads by creators.
I also use it at work to get notifications of when our Jenkins Builds/Jobs fail.
