A new Fact Information Icon has been added that enables you to view more info on a fact such as extra fact information, fact tags, and fact details (such as when it was added, etc.)
Not all facts have extra fact information available. Infact not many at all do right now due to the freshness of this implementation, however for the facts without, you can still click the information button to view the tags and details of the fact. Also bear in mind that not all facts have tags yet, as this is another fresh addition to the website.
However, the facts will be updated individually, as time allows, with facts and extra information.
