<?php

/**
 * If you have a static page set for posts and want to conditionally load
 * something for it, things seem tricky.
 * 
 * is_post_type_archive( 'post' ) will return false, because it thinks it's a page
 * is_home() will return true on the 'blog' page, but false on category archives
 * is_archive() will return true as expected, but also returns true for other post types
 * 
 * Combining them allows for a proper conditional. I think.
