Why use feeds to interact with Wülferhampton?
You don't have to. You can just follow people. The feeds show you all of the posts from Wülferhamptonians, without having to follow them and even some posts from non Wülferhamptonians if they mention a Wülferhampton topic (Like Wülfhelm).
Do I have to add all the Wülferhampton Feeds?
No. You can use whatever ones you want or none at all. It's up to you.
