Good article usage is intended as a large, random, careful survey of the language and style of Wikipedia editors. This is taking place at the level of Good Article nominations because that's where people are voluntarily submitting their work for review. This phase of the survey will end on April 30, and there won't be another phase unless or until we have more questions that need answering.
The language and style of Wikipedia editors varies depending on their background, the maturity level of the article, and the standards of the various wikiprojects. We are asking all the editors to tell us if they disagree with any of our suggested changes to markup, punctuation and language, and asking them a few background questions. The goal is to describe, in general terms, the range of language and style that editors prefer in Good Articles.
