It will likely take the form of a plain-text or markdown-based 'article sharing' app/protocol.

So it's essentially a web browser, but the initial wave of content found on it is pirated articles from commercial websites, unpaywalled, with ads and cruft stripped out.

And that's bolted atop a social graph for communal comments, maybe from Mastadon.

For years, I've been expecting this to show up. People hate ads, paywalls, and trolls so it scratches an itch, and there's a 'viral' spread from having existing users invite their friends by sharing article links.

It seems like a matter of time.
