Role in series
Horsesense is apparently a blog, onto which Foaly uploads information and gossip. It is apparently quite popular, and has been mentioned various times throughout the books.
The Opal Deception
In the very beginning of The Opal Deception, an article from www.horsesense.gnom is published. Foaly uploaded a behind the scenes account, mentioning how Holly Short was set up instead of actually being responsible for Julius Root's death and the subsequent events. Foaly praises Holly for saving the city, and criticizes the higher-up's blaming of her.
