According to Google Trends, during the past few years, there has been nothing but a few minor bumps that faded away as quickly as they came. I love RSS because i do not have to scroll through dozens of different news sites all day and i would love it to return.
EDIT: Typical case of people only reading the headline. I was asking why people are hyped over something that did NOT happen.

You would need an RSS reader, and then you subscribe to the RSS feeds in the reader and it will automatically fetch and aggregate articles / posts / videos / whatever content that gets published. There are browser plugins to do it, separate applications, and even websites like feedly and bazqux that do it. If you’re inclined you can even host your own RSS service with something like tt-rss or FreshRSS. Having a hosted service like feedly or bazqux or your own can be nice if you want access to your feeds on multiple device, with synchronization about which things you have already read / seen. I personally host my own FreshRSS instance and have connected to it with Reeder / Unread / NetNewsWire / Newsflash / the web interface.
An RSS feed is really just a simple file hosted on a website that basically just lists new content. RSS feed readers basically just automatically check these lists for updates. It’s pretty simple, but it’s really nice for subscribing to things you actually care about.
NetNewsWire is the client I recommend, if you’re on a platform that supports it. Feedly is pretty good and easier to get started with since it has a search index for various feeds
