It looks like after three years since the discussion took place on the WPTavern forums regarding the standardization of theme hooks, Doug Stewart has decided to put together a Theme Hook Alliance project to get theme authors all on the same page.
Child theme authors and plugin developers need a consistent set of entry points to allow for easy customization and altering of functionality. Core WordPress offers a suite of [action hooks](http://codex.wordpress.org/Plugin_API/Action_Reference/) and [template tags](http://codex.wordpress.org/Template_tags) but does not cover many of the common use cases. The Theme Hook Alliance is a community-driven effort to agree on a set of third-party action hooks that THA themes pledge to implement in order to give that desired consistency.
It will be interesting to see how far this goes and what the adoption rate will be like. Doug is looking for some feedback so if you’re keen to the idea, let him know in the comments of his blog post.
