If you like RSS, don't rely on Google. They'll probably kill it again [0] after this experiment runs its course, or wait until more people adopt it by default and then try to break yet another open standard.
If you'd like a recommendation, Feedbin is fantastic.
It’s dead.
Everything else has about or below a million of users.
80 millions is a lot, yes? We have 4660 million web users.
Twitter has 200 million users. TikTok has 700 million users. Instagram has 1000 million users. WhatsApp has 2000 million users. Facebook has 2701 million of users. Youtube 2740 million users.
All of those one-off platforms dwarf the supposedly ubiquitous RSS format, and all those one-off platforms have one-off apps with their own push notifications for content.
RSS is today a small niche. It's on a path to becoming like IRC, where a small core of people swear it's the most important thing ever, but actually they didn't get the memo that most everyone has moved on.
I'm not sure what you're trying to say. There's more people using internet now in general. Saying "it's absolutely irrelevant except to a small niche of users" is an egregious statement.
