Carthik‘s WordLog has a quite featureful entry today: Improving the Search Results Page. I will be implementing some or all of those suggestions in the near future. [When exactly? Your guess is at least as good as mine.]
If you thought that I’d note that Carthik linked to my Alternating Comments Classes hack of wp-comments.php, well, you’re right. I need to implement that here sometime, but I’m also re-thinking about how I present comments.
