Appeal to the emotions. Bring out laughter. Enrage. Make them blush. Crimson.
Craft sentences so they're annoyingly short or lovingly soft and long. Caress/destroy. Entice your readers, tease them, inspire them to feel.

Information should be fun and thought-provoking. Link to other images, different angles, your childhood, their childhood, progression, dreams, despair.
Make it personal.
