Policy on the use of contractions

[Luís Marques]

Ali, I have noticed that you, for the most part, avoided the use of contractions, such as contracting it is to it's. That's seems fine to me, even though that is more common in texts that are more formal than your book, which sounds more friendly, personal and informal.

What is your exact policy regarding this? Do you want to be consistent in avoiding contractions? I ask because there are still some contractions in the book, such as let's (let us). In a formal text you would also avoid those. Should we change those to avoid the contraction, and be consistent? Do we discuss them case by case?

Yes, the text is not that formal but let's keep it as is. According to my ears, although "it is" and "it has" are used in daily speech, nobody says "let us".

And I have a dislike for "it's" and friends because it is not immediately clear whether it is "is" or "has".
