One problem there is Wikipedia culture. Suppose you're a bona-fide content-area expert, fully capable of accurately conveying your knowledge in clear language that most people can understand. You might want to concentrate on creating the article.

Instead ... if the topic is not obscure and unpopular ... odds are high that you'll wind up jousting with dozens of inspired but unqualified challengers. The first time two of the paragraphs you've spent hours crafting disappear on someone's whim, you're probably going to stay gone.

"Anyone can edit"? In many cases, no. Take the 'Start-class' article 'performing arts', for example: how many people are truly qualified to summarize that enormous topic?

A-quality doesn't emerge from a melange of bits and pieces.
