 * I’ve seen some pretty fancy stuff done with add_filter, but I think what I want
   needs something else.
    I want to scan the post for keywords and replace them.
   But, say that I want to grab a link from another feed every time I mention the
   name of the feed. Now, I want to do this replacement before the post is put in
   the DB, because I need to use the link that appeared in the feed at the time 
   I posted, not at the time my post is viewed. (Am I clear?) What would I want 
   to use?

 * Okay, I think I’ll change the format_to_post function in functions.php, adding
   $content = apply_filters(‘format_to_post’, $content);
    And then I should be able
   to use my-hacks.php to define the specific stuff. `function format_to_post($content){
   global $post_autobr,$comment_autobr; $content = addslashes($content); if ($post_autobr
   || $comment_autobr) { $content = autobrize($content); } $content = apply_filters('
   format_to_post', $content); return $content; }

 * Good idea, I’ll add that.
