THA is about standardizing theme hooks in the wordpress community, so that plugin developers can easily hook into themes consistently. A great suggestion/movement and hopefully receives the support it deserves. Btu while we're at it, why don't we add other standards… sidebars or widget areas are in nearly all themes and each theme names them differently. Ever notice that switching themes clears all your widgets? If they were named consistently – they would remain intact. Menus seem to suffer the same flaw. Let's standardize them all in an effort to clean up our collective code and make things seamless! Follow the discussion by Doug Steward and Dougal.
