Does BTW assist in making a conversation better?

Yes, BTW is frequently employed to make the discourse less jerky, adding some side remarks or topics in a way that does not sound urgent. It functions as a conversation bridge whereby you find yourself diverting. An example of this would be when talking about work and you have remembered something that is not related, then you could tell the other person, BTW, you should not forget about that meeting tomorrow. This makes the conversation interesting and it assists in keeping the conversation relaxed. Nonetheless, it can be easily overused and, therefore, it is better to pay attention to it.
