[wp-hackers] Best Practice for hooking wp_insert_post()

[Otto]

I've had to do this a few times. The only way I found that doesn't
suck is to hook to transition_post_status like this:

add_action('transition_post_status','whatever',10,3);

Your whatever function will get $new, $old, $post, such that
$new = new post status ('publish')
$old = old post status
$post = the complete post object

By comparing new and old, you can determine if a post is being updated
or published or what.

Every other way I tried ended up with one-off anomalies.
