It is probably less than years ago, but its still a thing. In fact i heard youtube and other big sites (e.g. Reddit, etc.) still have rss feeds. Someone also told me that there is a bit of an uptick....buit this kind of thing is likely difficult to concretely quantify. As a single data point, I'm a fan of sites with RSS feeds...so i will frequent these sites more, and would be williung to pay for sites to have such a feature!
