I’m using Jerome’s Keywords plug-in for WordPress, but found that I didn’t want my entire list of Categories output to the meta keywords tag (it was a bit excessive and in my opinion, might push the limits of what a crawler will accept). The changes are simple and posted here in case you want to make them to your copy. For the function get_the_keywords() you can pass a boolean value (e.g., get_the_keywords(true); ) which indicates whether to include the categories in the keyword list. Default is to NOT include them.

N.B.This modification applies to version 1.3, it’s easy to adapt it to 1.4, and by 1.5 I think Jerome will already have included it.

function get_the_keywords($include_categories=false) {
	global $cache_categories, $post_meta_cache;
	
	$keywords = "";
	
	if (isset($cache_categories) && $include_categories) {
		foreach($cache_categories as $category)
			$keywordarray[$category->cat_name] += 1;
	}
	
	if (isset($post_meta_cache)) {
		foreach($post_meta_cache as $post_meta)
			$keywordarray[
	                 $post_meta[KEYWORDS_META][0] ] += 1;
	}
	
	if (isset($keywordarray)) {
		foreach($keywordarray as $key => $count) {
			if (!empty($keywords))
				$keywords .= ",";
			$keywords .= $key;
		}
	}
	
	return ($keywords);
}
