I like how the "likes" and "dislikes" are being distributed evenly by those who either do or don't know how to use their moka pot.
For the record - fill the coffee part with coffee, no half measures. Fill the bottom half up to just below the valve.
Anything else is, quite simply, wrong. Don't want to drink a full brew of coffee? Either keep the leftovers in the fridge and have a delicious iced coffee when you get home from work on a hot summer's day, or buy a smaller moka pot.
(Good Italian style iced coffee: put strong coffee, as much sugar as you need, some ice cubes, and half a teaspoon of egg white in a jam jar, put the lid on, shake like buggery. Pour into a small, chilled glass, it should look like Guinness)
