> The biggest cost of RSS feed items as a consumer is figuring out whether something is worth reading. A lot of feeds these days don't provide anything useful in the body to make a determination on this, and others just dump the entire contents in the body, which means you're wasting a bunch of time reading N% of something until you realize you're not interested in it and it can be skipped.

I think a big problem with this is that commercial websites believe that they have to update a million times a day to Feed the Algorithm™, which bloats their RSS feeds and any RSS reader you might have checking on it. Similarly, subscribing to a particularly active subreddit or three would also fill up your reader with trash.

I get a lot more use out of my RSS reader to check smaller, personal sites that don't update as often
