Informing them is a necessary evil. It is the part you don't want to do, but you must. It makes them work. People have to work to be informed, and I would much rather carry them along in an effortless experience.
When you inform, you have to serve it to the reader in the nicest, most interesting, rhythmic way you can.
Each paragraph is a sentence. The first sentence of the paragraph IS the paragraph. The rest of the paragraph explains the idea.
So... a speech with 5 paragraphs has one main idea that you repeat at the beginning and end.... and it has 3 sub-ideas.
