The TikTok model is about scrolling, skipping, being selective.
RSS readers should be treated the same way. "River of news" is an RSS thing. You dive in when stuff interests you, and you let what doesn't interest you flow by.
Twitter is basically an RSS-like reader with 120 character limits on posts. You subscribe to interesting people, and their little posts drop on your homepage in reverse chronological order. There's no inbox or unread items. You just scroll past to the next item that interests you.
Yeah, turning off unread-items counters, definitely. The value of RSS is in what you chose to read. It's not an anti-library. And if something is really great, a good subscription list means someone you're reading will likely mention it and link to it.
