I adore RSS! Use it literally every single day. I have many feeds on Feedly.com, and add to it every week or two.
Tip: use a service to stream quality content to your RSS feed reader. For Hacker News, http://hnapp.com/ does the trick for me.
I subscribe to a couple dozen authors on Hacker News.
Example: in hnapp, search for `author:bob1029`, there's an RSS link, paste that into your RSS feed reader to see that person's Hacker News comments.
I have an entire "Hacker News" section in Feedly, just with author's comments. Very useful!
