@anjou I use RSS feeds every day. Most of my internet readings outside of my job I do through RSS.
I use selfoss as it allows me to have the articles available anywhere, with a nice web interface and phone application.
Most websites I'm interested in provide an RSS feed, that is generally blogs and that sort of stuff.
If you search my profile, just the other day I found a website which offers the service to turn Facebook pages into RSS feeds.
As much as it is nice, I only keep essential stuff in my reader: I want to read pretty much everything that gets into my feed. This means I have to think a little bit up front to decide whether to add a site to my feeds, but while reading I don't have to think about what to read and what to discard; from time to time I prune my list of feeds removing stuff I'm not interested into anymore.
