It's fine to propose technical solutions like browser add-ons. But how does this address the problem of comment sections easily devolving into a dumpster fire? There's a reason why newspapers, like the Inquirer, are turning off their comment sections. That reason is sound. It's like hosting a block party and having it overrun by neighborhood maniacs, weirdos, libertarians and homeless people. What you're proposing is a means for inviting, organizing and publicizing commentary for all content on the web whether the content creator wants it or not.
