Wikipedia:Make articles useful for readers

One of Wikipedia's rules to consider:

Remember that the main purpose of Wikipedia is being useful for readers. Do whatever you see fit, if you think it will make Wikipedia more useful for readers. Try engaging in such Wikipedia-related activities that improve Wikipedia's usefulness most. You should decide yourself whether it's more important to write articles or to promote Wikipedia, whether it's more useful to write new articles, improve existing ones, organize indexes, etc.

A corollary: When you do write articles, consider the audience in your writing. An article entitled "Use of chromatic scales in early Baroque music" is likely to be read by musicians, and so technical details and jargon are entirely appropriate. But an article entitled "Rap music" is likely to be read by laymen who want a brief and plainly written overview, with links to more detailed information if available.
