For
Readers tracking major open problems and breakthrough claims
Worth noticing
Rumors are explicitly labeled, while source trails distinguish reporting, papers, discussions, and personal speculation.

Field notes

The homepage uses a watchlist structure rather than a conventional article feed, with active and completed states plus filters for three technical fields. Individual records attach a latest source and classify the development as a milestone, discussion, rumor, or paper. The featured Hodge Conjecture record is unusually explicit about separating a social-media user's assumption from what reporting confirms, giving the site a visible editorial rule for handling breakthrough claims.
