When it comes to an audience and trying to figure out the persuasion you may need. You need to know the kind of topic you are talking about and put a lot of emotion into how you put your words. I’d say keeping audience hooked can be a good thing, when you’re knowledgeable enough on the topic, you have more fun with it. Whether that be with manipulating it, wording it, etc.
Based on your attitude it can be used in many different ways, you can shape what you’re talking about into a modest tone, humorous tone, etc. It is all about the intention behind it, and your intention should be that the audience gets that. When speaking on a topic whether it be as valuable or not, you should always put your thought process into what could offend someone and what couldn’t. Quality over quantity is key when communicating to a certain audience.
