Call me old fashioned, but I think a speech should be something personal that reflects you and the person/people on the receiving end of the speech. If you do not know what to say, then maybe there is no need for a speech.
That being said, it could be helpful to some people that have something particular things on their mind, but unsure how to structure it into a speech.
Yeah, I agree. I would consider it rude to present the output straight from the tool. But if you use it as an advanced template that gives you structure it can be useful to overcome the blank page syndrome.
Nice job on finishing this project though!
