Good writing conveys information more clearly, of course, but the reader isn’t the only beneficiary. Writing also makes us better thinkers. Even a talented wordsmith must first clarify his thoughts and eliminate ambiguity to make a convincing argument.

This is a really good reading to… have some tips on how to write. He gives a few very interesting advice, and the article is a very nice summary of techniques.

Some good advice he gives:

1. Read lots: reading others helps build your skills, and even more helps to identify and study good writers (and UIs) and bad ones.
2. Make every word matter: or, in other words, remove the superfluous.
3. Cut adjectives and adverbs: this is a great advice, suggesting to use more descriptive verbs instead of generic ones.
4. Active verbs, not passive: this is a simple rule to put the reader at the center
5. Monster sentences: short sentences, to the point. Avoid lots of conjunctions.
6. Singulars and plurals: this is simple, you just have everything match.
7. Occam’s Razor: prefer simple explanations over complex ones, simple structures over complex ones, avoid buzzwords.
8. Vary pace: use paragraphs well, alternate their length and tempo.
9. Proof your work: reading aloud is very helpful.

This writing reminded me a very interesting and basic rule when you design interfaces buttons and interactors: always use subject and verb, at minimum.

This is very simple, and helps create a better understanding. To give an example, to you think it’s clearer to have a button that say “Add” or “Add post”? As any rule, when you master it you can break it, but it’s always important to keep it in mind.
