This article Analysis Services Event ID and Event Descriptions is a great example of community working together to create and update an article. This article has been revised by several different community members and even translated into Brazilian Portugese. There are also plenty of comments about how helpful the article is to people. Another impressive item to me about this article is that it is zero on fluff, it goes right into telling you what it promises: Event IDs and Event Descriptions. The bit of extra information that it does contain are links to the software that is referenced and links to additional Event Log information. The article is beautiful in its simplicity and function.
A real community win!
