@Theby really it depends on the type of responses you are seeking.
If you wish to have a solid response and dialogue only about the subject you have posted then General is the way to go. Questions such as “My cat is acting lethargic- could he be sick?” you would most likely want to have only helpful responses on.
If it is a casual question such as “Why do you love your cat?” you will want social because you will get responses that are not edited if they wander off topic or are humorous without being helpful.
