I didn't find anything related to what i'm trying to do.
My WP blog have several categories. For one specific category, in which I publish short news and viral content, I'd like to use Facebook comments as the default commenting system.
For any other categories, i'd like to keep using Disqus as usual.
My problem : since Disqus is taking over with a hook (I guess), how can I have Facebook comments take over instead of Disqus if in_category(x) ? Where would that happen, and how would you do ?
(Ideally, i'd like to deal with it in functions.php instead of having to edit core Disqus plugin files)
