How can I get the meta description to show in the head of the page?

With recent changes to Add Meta Tags, it is now completely possible to make it work good with AnsPress. I’m using it, see it in action here: http://dima.stefantsov.com/qa/

add_action('wp', 'd_anspress_amt_fix');
function d_anspress_amt_fix()
{
    // Only make changes when inside AnsPress.
    if (!function_exists('is_anspress') || !is_anspress()) {
        return;
    }


    add_filter('amt_exclude_schemaorg_metadata', '__return_true');
    add_filter('amt_exclude_dublin_core_metadata', '__return_true');

    // Feed AMT with real question-post.
    if (is_question()) {
        add_filter('amt_get_queried_object', function(){ return get_post(get_question_id(), OBJECT); });
    }
}
