Reading other people's Hubs, especially those of fans, would only matter if you have an interest in what they themselves write. Just because someone fans you, doesn't mean you have to read their stuff. They fanned you, because they like your writing.
I thought that is what it means to be a fan of someone's writing. If I am mistaken, please do tell.
Btw- I do visit some of my fans Hubs. I have similar interests as those who read my writing. I'm always glad when I learn something new from one of them and I am grateful for the knowledge.
I don't get to as many as I would like, but then again, I don't read everyone's Hubs, who fanned me either. They found something in my writing, which is why they fanned me.
