Although I still have Feedly on my phone, and open it occasionally, RSS readers are not as useful as they used to be. That is not due to the way RSS inherently works, but in the past 15 years, websites no longer make their entire articles available on the feed. What you usually get is a small excerpt with a link to the website. They do that because RSS does not allow for the same level of engagement and advertising they would have on their website. As it is, RSS readers are, technically, link aggregators. Which makes them much less convenient.
