The WPBeginner site has unveiled a new resource for WordPressers: a glossary. WordPress resources are abundant online, but there has not been a canonical glossary on the subject - the Codex is good for what it does, but it is not a glossary. WPBeginner have taken the initiative to create a centralized listing of WordPress-related terms, along with their definitions, and link to related content as appropriate (good SEO win for WPBeginners as well). It's a good start, but there's much more that can be added; the people behind the site are open to suggestions! They are also interested in volunteers to help with managing the glossary.
