I love RSS and I actively used it until modern browsers dropped support for it and then websites stopped using it. I always felt RSS being dropped wasn’t the choice of users but more a conspiracy between those browser developers (or rather their managers and company leaders) and marketing/sales departments of pretty much any company that advertises on the internet: Google being the main one.
Why? You can’t bombard RSS with advertising like you can on browsers and if people could get the information they need from RSS they won’t see ads.
I recall the dropping of RSS happened over 6 months to my recollection. RSS was here and every website of merit used it, then all of a sudden Chrome, FireFox and Safari all dropped RSS support. You could go and install a separate RSS client but few people did that (extra steps and all) and then websites saw no one was using RSS and dropped support.
RSS was particularly useful for browsing jobs for IT contractors. I used it daily, using RSS I was able to get job listings fast and apply before other candidates.
