Last year Chris Coyier posted an article titled "May is Maintenance Month". Chris' idea was to rewrite older articles to keep the resource (his website) up to date. I didn't join him in doing so last year — mostly because css-plus was still very new at that point. This year, however, I am supporting the fight against old/outdated articles. I'll mention that the article was rewritten and also refer to the original date.
