Many sites now contain user-generated content that is added to the primary content of a page, usually called “comments.”
Many users want control over whether they see this content; it is often viewed as distracting, distasteful, and in some cases, damaging. “Ignore the comments” has become a shorthand for acknowledging that allowing people to add their thoughts to more well-researched content often results in an overall lowering of quality, as well as a waste of time for users.
The Web platform should give users control over whether they see content that they might perceive as low-value. A new HTML
<comments> element would allow sites to mark up this kind of content so that browsers and other user agents could automatically remove it, if the user expresses a desire to do so.
This is better than site-by-site preferences, which are onerous.
Initial implementation in browsers could be done in extensions. The exact semantic of
<comments> would be need to be carefully described, so that it was clear that if the primary content of a site were user-generated content, it would not apply (but comments on that content might be in-scope).
