Matters not. Just give good and polite answers and you'll have people following you anyway. Whether you choose to follow back is completely up to you. No one is keeping score and you don't get anything more. It's not a popularity contest. Answer questions and have fun !
It's obviously your choice. I follow people because they give good & constructive advice. I even like the jokesters. If you get tired of following people or having them follow you, you can always block them.
