After deliberating for a month or two, I’ve finally upgraded this blog to WordPress 2.02. A Spam Karma upgrade was applied too.
One thing I would note, and this is a point well made elsewhere, if you are using Google AdSense make sure that your AdSense code is protected from WordPress’s new Preview feature. Easily achieved using something similar to this (lines 1 and 9 are the lines to look out for):
< ?php global $wp_query; if (!$wp_query->is_preview): ?>
