One of the great things about our industry is how passionate people are about helping each other learn. Be it articles about the latest and greatest techniques that they’ve discovered, or blog posts about new web platform features that have landed in modern browsers. All this content–often created by people in their spare time–has one downside: it is often unmaintained, and with the frequency that certain features or APIs can change syntax or new prefixed implementations arrive, the content can become outdated. If the content appears high up in search results, or is linked from influential sources, it can lead to developers copying code that may not work in as many browsers as it could. It can also harm the adoption of the latest version of the spec.
