Venerated style guides like the AP have long been the go-to source for resolving arguments and maintaining consistency across the written word, but the internet is a different publishing platform. Yahoo's Style Guide wants to be the style guide for the digital world.
The site's full moniker, Yahoo Style Guide: Writing , Editing and Creating for the Digital World, tackles everything from common usage ("email" instead of "e-mail") to more obscure digital-specific topics, like user-interface text.
As with any style guide, nothing's written in stone — just because Yahoo or AP declares a style doesn't mean it's the only correct way (sorry Yahoo, but we're sticking with "internet" rather than "Internet") — but if you don't already have a strong opinion on digital style or just want to adopt a standard in your digital writing, it's a good resource to consider. They're also selling the book for around $US15 on Amazon if you're eager to fill an empty space on your desk. Otherwise the entire content is always available online.
